Toning · Atlas

1. Introduction

Version followed: Laurel Elizabeth Keyes's toning as summarised from Toning: The Creative Power of the Voice (copyright 1973, DeVorss; the book itself is not drawn on), together with its clinical uptake as a core technique in Diane Austin's vocal psychotherapy (Austin 2008, as reviewed by Wright 2016) and the open-vowel toning protocol of Bernardi et al. (2017). Where these differ, the guide names the version. [source: Wikipedia, Bookshare, Wright 2016, Bernardi et al. 2017]

What it is. Toning is wordless, sustained vocal sound made on the out-breath: a sigh, groan, hum or long open vowel that the person lets come out rather than composing. Keyes presented it as an ancient healing method that anyone who can groan can do. She said it needs no special gift, faith or religion, and that it works with what she called the body's natural energy flows. [source: Bookshare synopsis of Keyes 1973] A later edition (DeVorss, 2007/2008) is co-authored and expanded by Don Campbell and adds a CD. One unsourced note says this edition departs from Keyes's original wording, so this guide names Keyes 1973 and the Campbell edition separately. [source: Foyles; Winstone; Wikipedia] [uncertain: the book is sometimes dated to 1964, but the sources give a 1973 copyright; no 1964 edition is documented.]

Status. Keyes's toning belongs to New Age and metaphysical sound healing. It is not a clinical method with a manual, a training standard or a regulated practitioner title. Keyes was a writer, lecturer and lay-religious retreat leader who blended psychology with metaphysics, not a clinician. [source: Wikipedia] Claims that toning rebalances energies, restores health or heals ailments are the claims of Keyes, Campbell and sound-healing groups, not established findings. Toning is not a treatment for any physical disease, and nothing in this guide should be offered to clients as one. [source: Wikipedia; Winstone] Within psychotherapy, toning is used as a breath-and-voice technique inside vocal psychotherapy and music therapy. [source: Wright 2016; Austin interview 2011; Meashey 2020 via Eyre 2021]

How change is thought to happen. There are three accounts, and each should be attributed to its source. (a) Keyes's account: sound vibration soothes and nurtures the body's interior and releases tension, and the groan is a natural, unthought relief response. She put it this way: "one does not think a groan" (Keyes 2008, p. 26, quoted in Wright 2016). (b) The vocal-psychotherapy account: sustained sound grounds the client in the present. It gives pre-verbal feeling such as grief a voice, and can soften defences so that unconscious material surfaces and can be discussed. Shared sound builds intimacy and safety in the relationship. [source: Austin 2008 via Wright 2016; Austin interview 2011] (c) The physiological finding: toning spontaneously slows breathing to about 6 breaths per minute and raises heart-rate variability. A matched silent-breathing condition produced similar effects, so the authors attribute the effect to the breathing rather than to the sound. [source: Bernardi et al. 2017]

2. Framework

Toning has no published phase model, session count or progression criteria. The sources describe it as a technique placed inside a session, not as a stand-alone course of therapy. [source: Wright 2016; Austin interview 2011] The structure below orders what the sources describe. The phase labels and the criteria for moving on are [synthesis].

Professional frame. Practising "toning" requires no regulated profession, credential or registration. Sound-healing classes are unregulated. [source: Gumroad class listing; Wikipedia, showing lay study groups] When toning is used as therapy, the frame is that of the practitioner's own registration. In the UK that means music therapists registered with the HCPC (professional body BAMT). In the US it means MT-BC credentialed by CBMT (professional body AMTA). For psychotherapists it is their own licensing body. [synthesis] Austin describes deeper vocal work, such as free associative singing, as advanced work that needs personal therapy, supervision and "resilient boundaries". [source: Austin interview 2011] Simple breath-and-tone grounding (4.1–4.4) is within a psychotherapist's ordinary competence. Use regressive, trauma-processing vocal methods (4.8–4.10) only with music-therapy or vocal-psychotherapy training and supervision. [synthesis]

Phase A: Orientation and consent (first session in which toning is offered). Goals: explain toning in plain terms, including that the health claims are Keyes's own. Screen for contraindications and voice-related triggers (section 5). Gain explicit consent and agree a stop signal. Move on when the client understands that sound is optional and agrees to try. [synthesis; client choice to decline: Thiermann 2011 via Wright 2016]

Phase B: Warm-up and breath (2–5 minutes, early in the session). Goals: settle the breath and lower self-consciousness. Austin places warm-ups such as lip trills, sirens and melodic mirroring before toning, and places toning at the start of a session before singing or vocal improvisation. [source: Austin 2008 via Wright 2016] Move on when the client breathes freely and can make some sound without marked embarrassment. [synthesis]

Phase C: Toning proper (about 3–10 minutes). Goals: sustained, unforced sound on the exhale, with present-moment attention to breath, vibration and feeling. Bernardi's protocol ran 7 minutes of seated toning. [source: Bernardi et al. 2017] Austin lets the sound "go wherever it needs to" until the client feels more grounded. [source: Austin interview 2011]

Phase D: Deepening (optional; trained clinicians only). Goals: give voice to wordless feeling. This uses primal sounds, vocal holding over a drone or two chords, and therapist joining in sound. [source: Austin interview 2011; Austin 2008 via Wright 2016; Meashey 2020 via Eyre 2021]

Phase E: Return and processing (at least 5–10 minutes before the session ends). Goals: re-orient, then talk about what surfaced, since altered states and unconscious material may emerge. [source: Austin 1996 cited in Austin 2008 via Wright 2016] Close the session only when the client is oriented and regulated. [synthesis]

Format. Individual dyadic work is the format the clinical sources describe. Toning also runs as lay groups and classes. [source: Wright 2016; Gumroad class listing] Group toning in therapy is [synthesis]. Frequency: use it as a recurring opening ritual or as needed. The anxious client Austin describes began every session with a breath and a sustained sound. [source: Austin interview 2011]

3. Guiding principles

Natural, not performed. Keyes's core instruction is to let the voice express itself in a natural way. Practical meaning: never correct pitch or tone quality, and treat a groan as a valid tone. [source: Bookshare synopsis of Keyes 1973]
Anyone can do it. Keyes held that toning is a learnable skill, not a gift. Practical meaning: frame it as "if you can sigh, you can do this", and remove any performance standard. [source: Bookshare synopsis]
Not about a beautiful voice. Austin says of vocal holding that it is "not about having a beautiful voice." Practical meaning: model imperfect, relaxed sound yourself. [source: Austin interview 2011]
Breath first. Breath is central to the work, and the measured effects track breathing. Practical meaning: start with breath, watch the breath throughout, and allow silent breathing as a full alternative. [source: Austin interview 2011; Bernardi et al. 2017]
Safety and choice before sound. Clients need to feel safe to make sound and must be free to decline. Toning does not work when the client feels unsafe. Practical meaning: get explicit consent, agree a stop signal, and offer a silent option. [source: Thiermann 2011 and Wright 2016 via Wright 2016]
Relationship is the vehicle. Austin sees the relationship as the core of healing and "connection" as what she most looks for. Practical meaning: attend to the contact between you, not to the sound as such. [source: Austin interview 2011]
Not a recipe. Austin stresses that vocal holding "is NOT and never should be a recipe." Some clients need a structured song or words first. Practical meaning: adapt, and drop toning if it does not fit. [source: Austin interview 2011]
Join to reduce shame. The therapist may tone with the client to lower self-consciousness. Practical meaning: offer to sound together at first, then gradually step back. [source: Austin 2008 via Wright 2016]
Present-moment, non-judgmental attention. Toning is used to invite moment-by-moment, non-judgmental awareness. Practical meaning: guide attention to vibration, breath and feeling, without analysis while sounding. [source: Bernardi et al. 2017; Austin 2008 via Wright 2016]
Process what emerges. Toning can induce altered states that bring unconscious content to awareness, which is then discussed in therapy. Practical meaning: always leave time to talk afterwards. [source: Austin 1996 cited via Wright 2016]
Therapist resilience and boundaries. Intimacy in shared sound requires skill to hold boundaries. The therapist must be able to feel intense emotion without being overwhelmed. Practical meaning: use supervision and watch your own voice for countertransference. [source: Austin 2008 via Wright 2016; Austin interview 2011]
Attribute the metaphysics. Energy and healing language is Keyes's and Campbell's theory. Practical meaning: say "Keyes believed…" and never promise physical healing. [source: Wikipedia; Winstone; synthesis]

4. Intervention inventory

The sources describe the techniques below. The steps are written in this guide's own words. Where a source gives only the outline, the operational detail is marked [synthesis]. Keyes's own step-by-step exercises are not drawn on, so no exercise is attributed to her beyond what the summaries and quotations support. [uncertain]

4.1 Breath settling and attuned breathing

Purpose / when: opens any toning work. Also for clients who hold their breath, dissociate or stay "in their heads". Austin calls the breath "so important". When a client holds their breath, she breathes audibly herself, which clients often follow, or she invites a breath directly. She also matches her breathing to the client's so that the two of you breathe together. [source: Austin interview 2011]
Steps: (1) Seat the client comfortably, feet on the floor, eyes open or lowered as they prefer. [synthesis] (2) Invite a few slow breaths, with the out-breath a little longer than the in-breath. [synthesis] (3) If the client holds their breath, breathe audibly yourself, or say so gently. (4) Match your rhythm to theirs for a minute. [source: Austin interview 2011] (5) Ask what they notice in the body. [synthesis]
Example language (illustrative): "Let's just breathe for a moment. You don't need to do anything special. Let the out-breath be a bit longer… I noticed the breath stopped there; let's take one together."
Watch for: dizziness or tingling from over-breathing. If it appears, return to normal breathing (section 5). [synthesis] Signs it is working: slower, fuller breathing, shoulders dropping, the client reporting more body awareness.

4.2 Vocal warm-ups: lip trills, sirens, melodic mirroring

Purpose / when: before toning, to loosen the voice and lower self-consciousness. Austin places these warm-ups ahead of toning; they are preparation, not toning itself. [source: Austin 2008 via Wright 2016]
Steps: (1) Lip trill ("motor lips"): blow air through loosely closed lips so that they flutter, adding a little voice if comfortable. (2) Siren: glide the voice smoothly from low to high and back on an "oo" or "ng", staying quiet and within a comfortable range. (3) Melodic mirroring: the therapist sings a short wordless phrase and the client echoes it, then the roles swap. Do each for 30–60 seconds and do them together first. [technique names: Austin 2008 via Wright 2016; the operational detail is synthesis]
Example language (illustrative): "This will sound silly, and that's the point. Let your lips flutter like a motorboat… now let your voice slide up like a siren and back down, as quiet as you like."
Watch for: laughter, which usually helps; strain or pushing high; shame. Keep the volume low and the range comfortable, and stop if the throat hurts. [synthesis] Signs it is working: laughter, the voice getting easier, more willingness to sound.

4.3 Natural toning: "let the voice express itself" (Keyes's version)

Purpose / when: the basic form as Keyes framed it, for releasing tension and making contact with the body. Keyes taught that the voice should be allowed to express itself naturally, and that anyone who can groan can tone. She regarded groaning as a natural relief response: "one does not think a groan." She described the sound's vibration as soothing and nurturing the body's interior. These are her beliefs, not established findings. [source: Bookshare synopsis of Keyes 1973; Keyes quoted in Wright 2016]
Steps [operational detail is synthesis; Keyes's exact sequence]: (1) After breath settling (4.1), invite the client to let a sound ride out on the exhale, such as a sigh or a low groan, without choosing a note. (2) Encourage them to let the sound find its own pitch, length and vowel, then stop and breathe in naturally. (3) Repeat over several breaths, inviting attention to where the vibration is felt. (4) Allow the sound to change as it wants to. (5) Pause in silence and invite the client to notice the after-effect.
Example language (illustrative): "If you can sigh, you can do this. On the next out-breath, let a sound come with it, any sound at all. A groan is fine. You don't need to decide the note; let the breath carry it." When explaining the theory: "Laurel Keyes, who wrote about toning, believed the vibration releases tension. You can just notice what you find."
Watch for: clients who perform or control the sound (see 5.2), and clients who hear this as a cure for a physical illness. Correct the latter plainly (section 5). [synthesis] Signs it is working: the sound becomes freer and longer, breathing deepens, and the client reports ease or feeling.

4.4 Breath-led emergent tone at the start of a session (Austin's version)

Purpose / when: a grounding opener, used before singing or vocal improvisation. With an anxious client Austin begins each session this way. [source: Austin 2008 via Wright 2016; Austin interview 2011]
Steps: (1) The client breathes in and out several times. (2) On the last few exhales, a sound is allowed to come. (3) The sound usually lengthens over successive breaths, and this lengthening grounds the client in the present. [source: Austin 2008 via Wright 2016] (4) For anxious clients, start with one deep breath and one exhaled sustained sound, then let the sound go where it needs to, as emotional release, until the client feels more grounded. [source: Austin interview 2011] (5) Check how grounded the client is before moving on. [synthesis]
Example language (illustrative): "Let's begin the way we usually do: a few breaths, and when you're ready, let a sound come out on the breath. Let it go wherever it wants to go, and we'll stop when you feel more settled."
Watch for: the sound shifting into fear, sadness, grief or anger, which Austin reports is common with natural sounds. Slow down and stay with the client. [source: Austin interview 2011] Signs it is working: the client says they feel "here" or settled, and their speech after sounding is slower and more connected.

4.5 Open-vowel exhale toning (Bernardi et al. protocol version)

Purpose / when: a structured, low-threshold form for regulation, breath slowing and present-moment attention, suitable for untrained adults. In the study, toning slowed breathing to about 6.2 breaths per minute (from 14.1 at baseline) and raised heart-rate variability more than singing did. [source: Bernardi et al. 2017]
Steps: (1) Seated, eyes open. (2) Voice the whole length of each exhalation on a freely chosen pitch, using an open vowel (for example "ah", "oh" or "oo"). (3) With each breath, either change the pitch and vowel or repeat the same one. (4) Continue for up to about 7 minutes, the length of the study condition. [source: Bernardi et al. 2017] (5) Demonstrate first; the study used a recorded example paced at about 4.6 breaths per minute. [source: Bernardi et al. 2017] The demonstration's slow pace may itself shape the client's breathing, so demonstrate unhurried, comfortable breaths. [synthesis from the study's limitation]
Example language (illustrative): "Breathe in comfortably. As you breathe out, let an open sound like 'ah' or 'oh' last as long as the breath does, on any note. Next breath, you can keep the same sound or change it."
Watch for: air hunger from forcing very long exhales; let breaths be comfortable. [synthesis] The authors suggest that vocalising may guard against hyperventilation at faster breathing rates. [source: Bernardi et al. 2017] Signs it is working: slower, deeper breathing and a calmer report afterwards.

4.6 Silent paced breathing (alternative to sounding)

Purpose / when: for clients who decline to vocalise, feel ashamed, have voice problems, or are in a setting where sound is not possible. In the study, silent breathing matched to the toning rhythm produced similar cardiorespiratory effects, and the authors note that silent paced breathing may be as effective as, or more effective than, the vocal conditions for heart-rate variability. [source: Bernardi et al. 2017]
Steps: (1) Breathe with the same slow, long out-breath used in toning, but silently, or with only an audible sigh of air. (2) Continue for a few minutes. (3) Offer sound again later only if the client wants it. [steps: synthesis based on Bernardi et al. 2017]
Example language (illustrative): "You don't have to make any sound. We can do the same long, slow breath silently, and you'll get much of the same settling."
Watch for: the client feeling they have "failed". Frame the silent version as complete in itself. [synthesis]

4.7 Therapist joining in sound

Purpose / when: to reduce self-consciousness when a client is too embarrassed to sound alone, and to build closeness through shared vibration. [source: Austin 2008 via Wright 2016] Austin describes singing together as "the most intimate kind of musical experience", partly because breath and vibration are shared. [source: Austin interview 2011]
Steps: (1) Offer to tone together, and ask permission. (2) Start on a comfortable low note at a soft volume. (3) Let the client choose the vowel and either match it or hold a supporting note. (4) Gradually soften your sound so that the client's voice leads. [steps 2–4: synthesis] (5) Notice your own voice; Austin reports her voice can reveal countertransference (for example, a judgmental tone) and that she took this to supervision. [source: Austin interview 2011]
Example language (illustrative): "Would it be easier if I make the sound with you to begin with? I'll go quietly, and you can let yours sit inside mine."
Watch for: the client relying on your voice indefinitely, and intimacy that feels intrusive to them. Check in about distance and offer to sit further apart or angle your chairs. [synthesis] Signs it is working: the client's voice emerges and holds on its own.

4.8 Natural and primal sounds: sigh, groan, moan, wail, scream (trained clinicians)

Purpose / when: to give voice to pre-verbal feeling in clients whose talking therapy has stayed in their heads. Austin works with basic sounds such as groaning, sighing, moaning, screaming and wailing, which often shift into fear, sadness, grief or anger. She calls this "similar to toning, but it's more primal." [source: Austin interview 2011] Use it only with music-therapy or vocal-psychotherapy training, supervision and a stabilised client. [synthesis]
Steps: (1) Agree in advance which sounds are acceptable, the volume limits (see hearing and voice safety in 5.7), and the stop signal. (2) Begin with sigh and groan, which are low-intensity. (3) Follow the client's sound and do not push towards louder or more extreme sounds. (4) When a feeling emerges, slow down, stay present, and allow silence. (5) Return to breath (4.1), then process (4.11). [steps: synthesis; sound types and emotional shift: Austin interview 2011]
Example language (illustrative): "You've described this as a weight with no words. Would you be willing to let that weight make a sound, maybe a groan, and see what happens? We can stop at any moment."
Watch for: flooding, dissociation, and voice strain from screaming. If the client disconnects, Austin's practice of breathing and moving together afterwards can help them return to their body. [source: Austin interview 2011] Signs it is working: feeling expressed and then easing, with relief and a sense of wholeness afterwards. [source: Austin 2008 via Wright 2016]

4.9 Toning to "sound the self" in deep emotional pain

Purpose / when: to voice pain without words when words feel meaningless and too much sound or music feels oppressive (for example, in grief). Meashey describes using toning to "sound the self". [source: Meashey 2020, as reviewed by Eyre 2021] Austin links toning to feeling grief and then releasing it, and quotes a student who felt more connected to their body and breath, and able to feel grief. [source: Austin 2008 via Wright 2016]
Steps: (1) Keep the environment quiet: no accompaniment or minimal accompaniment. (2) Invite one soft, long tone on the out-breath, at whatever pitch the pain seems to have. (3) Let tones repeat with silence between them. (4) Allow tears; continue or pause at the client's pace. (5) End with silence and a few plain words. [steps: synthesis; rationale: Meashey via Eyre 2021]
Example language (illustrative): "There may not be words for this right now. If you'd like, you can let the sadness have a sound, as quiet as a breath. I'm right here."
Watch for: spiralling despair as opposed to release. Check for safety and risk if the client voices hopelessness (5.5). [synthesis]

4.10 Vocal holding (Austin; trained clinicians)

Purpose / when: a related core technique of vocal psychotherapy, often entered from toning. The therapist uses two chords or a drone together with their voice to create a stable, consistent, safe musical environment, mainly to form a bond or give a reparative experience. Austin describes it as "ideal" for building a positive mother–child transference. [source: Austin interview 2011] It requires vocal-psychotherapy training. Austin stresses it is not a recipe. [source: Austin interview 2011]
Steps: (1) Play two simple alternating chords, or hold a drone, in a gentle, rocking, lullaby-like rhythm. Keep the harmony simple so the client's mind is not tracking chord changes and they can let go and feel the vibration. (2) Invite the client to sing any vowel they like, such as "ahh" or "oooh". (3) Sing with them. Austin maps unison, harmony and returning to the tonic onto stages of infant–mother development. (4) Follow the client's lead. [source: Austin interview 2011]
Example language (illustrative): "I'll keep playing these two chords. Whenever you like, join in on any vowel. There's no right note, and I'll be singing with you."
Watch for: strong regression or dependency in the transference, which needs supervision. If the client is not ready for this, Austin's alternative is a structured song or improvised words first. [source: Austin interview 2011]

4.11 Post-toning processing

Purpose / when: after every toning segment. Austin suggests toning and chanting can induce an altered state that brings unconscious content into awareness, and that this content is then discussed in therapy. [source: Austin 1996 cited in Austin 2008 via Wright 2016]
Steps: (1) Allow 20–60 seconds of silence. (2) Re-orient the client: eyes open, feet on the floor, name something they can see. (3) Ask open questions about sensation, image, memory and feeling. (4) Link what emerged to the client's therapy goals. (5) Note any changes for next time. [steps: synthesis]
Example language (illustrative): "Take your time coming back. What did you notice, in your body or in images or memories? … Where did the sound seem to come from?"
Watch for: spaciness at the end of the session. Do not end until the client is oriented (5.3). [synthesis]

4.12 Group toning (adaptation) [synthesis]

Purpose / when: toning is widely run as lay classes and study groups. [source: Wikipedia; Gumroad class listing] A psychotherapist may adapt it as a short, shared regulation opener in a therapy group. The clinical procedure below is [synthesis].
Steps: (1) Explain the exercise, attribute its claims, and state the opt-out (participants may breathe silently). (2) Arrange chairs in a circle with space between them. (3) Lead 4.1 and then 4.5 for 2–5 minutes at a soft volume. (4) Close with silence, then optional sharing.
Example language (illustrative): "We'll each breathe out on a long, quiet sound. If you'd rather breathe silently, that's fully part of it. Your sound doesn't have to match anyone else's."
Watch for: volume escalating in a small room, and members who feel exposed. Keep it brief and quiet.

5. Handling problems

The sources give little explicit guidance on problems. Austin's points about safety, choice and boundaries are cited where they apply. Everything else in this section is [synthesis].

5.1 Embarrassment, self-consciousness, refusal

Expect this; making sound in front of another person is exposing. Respond by normalising it, joining in sound (4.7), starting with lip trills or sighs (4.2), turning your chairs to face partly away, or offering silent breathing (4.6). Clients must be free to decline. [source: Thiermann 2011 via Wright 2016; responses: synthesis]
Austin notes that clients are often surprised to enjoy free, playful sounds that had been repressed for want of a suitable setting. Mention this to hesitant clients, framed as a possibility rather than a promise. [source: Austin 2008 via Wright 2016]
If a client declines repeatedly, drop toning. It is optional, and pressing it damages safety. [synthesis; principle from Wright 2016]

5.2 Performing, controlling or "doing it right"

Signs: choosing pretty notes, apologising for the sound, asking whether it was correct. Respond by restating Keyes's point that the voice is allowed to express itself naturally. Invite a groan or sigh, which is hard to perform. Do not praise the sound's beauty; reflect what the client felt instead. [source: Keyes via Bookshare and Wright 2016; responses: synthesis]
With music-trained clients, use the non-dominant hand on the belly, eyes lowered, and sounds outside their usual range or genre. [synthesis]

5.3 Overwhelm, flooding, dissociation, altered states

Natural sounds often shift into fear, grief or anger, and toning can induce altered states. [source: Austin interview 2011; Austin 1996 via Wright 2016] If distress escalates: stop the sound and orient (open eyes, name five things in the room, feel the feet). Use normal speech rhythm and lengthen the exhale silently. [synthesis]
For dissociation: Austin uses breathing and moving together to help clients come back into their bodies. [source: Austin interview 2011] Add standing, walking or pressing the feet into the floor. [synthesis]
Pacing: with trauma clients, keep tones short and few at first, and avoid primal sounds (4.8) and vocal holding (4.10) until the client is stabilised. The therapist must be able to stay with intense emotion without being overwhelmed. [source: Austin 2008 via Wright 2016; pacing: synthesis]
Leave time for 4.11 every time, and never end a session in an altered state. [synthesis]

5.4 Ruptures and boundary issues

Shared sound creates intimacy, which needs skilled boundary-holding. [source: Austin 2008 via Wright 2016] If a client feels intruded on, too close, or exposed: name it, apologise, and restore distance (stop joining in, sit further apart, return to talking). Explore the experience together. [synthesis]
Your own voice may convey judgment or countertransference. Austin identified this in her own speaking voice and took it to supervision. Do the same. [source: Austin interview 2011]
Strong regressive transference after vocal holding belongs in supervision with a trained vocal psychotherapist or music therapist. [synthesis]

5.5 Risk, physical-health and belief issues

Health claims: Keyes, Campbell, some sound-healing groups and some clinicians have linked toning to restoring health from ailments. Gaynor, an oncologist, integrated "giving voice" to ailments into his practice. [source: Wikipedia; Wright 2016] If a client hopes toning will treat a physical disease (cancer, pain conditions, infection), say plainly that it is not a treatment for physical disease. It may help with relaxation, breathing and feeling, and medical care continues as advised by their doctors. Never suggest it in place of medical treatment. [synthesis]
Spiritual framing: Keyes linked toning to energy flows and to ideas about humanity's relationship to God. [source: Bookshare synopsis] Present these as her beliefs. Respect clients who hold them, and do not impose them on clients who do not. [synthesis]
Suicide or self-harm disclosures during or after toning: pause the exercise and follow your standard risk assessment and safety planning. [synthesis]

5.6 Non-adherence to home practice

The sources give no home-practice protocol. [not found] If you set home toning: agree 2–5 minutes, a private time and a quiet volume, and offer silent breathing (4.6) when privacy is lacking. Review what happened rather than whether it was done. If the client feels self-conscious at home, a short recording of your own demonstration voice can help. [synthesis]

5.7 Modality-specific: voice, breath, hearing safety and musical triggers

Over-breathing: long, deep exhales repeated many times can cause light-headedness or tingling. Keep breaths comfortable, stop if dizzy, and do it seated. [synthesis; slow-breathing physiology: Bernardi et al. 2017]
Voice health: no pushing, shouting or screaming without training and agreed limits. Warm up (4.2), keep within a comfortable range, and stop at throat pain or hoarseness. Offer water. For clients with voice disorders, recent throat surgery, or breathing conditions such as asthma or COPD, use silent breathing or get medical advice first. [synthesis]
Hearing safety: individual toning is normally quiet. Loud primal sounds such as screaming and wailing, groups in small reflective rooms, or toning combined with gongs, bowls or amplified drones can reach uncomfortable levels. Keep volume conversational, sit apart, and leave the client control of loudness. Do not sound loudly close to anyone's ear, and take extra care with clients who have hyperacusis or tinnitus. [synthesis]
Musical and vocal trauma triggers: screen for experiences such as being silenced or punished for making noise, abuse in which sounds were involved or the person was made to keep quiet, humiliation in choirs, auditions or singing lessons, and coercive religious chanting. Sustained drones, hums or chant-like tones may evoke these, as may being sung to (4.10). Ask directly before starting. Offer alternatives (silent breath, client-chosen sounds, no drone), and stop if trauma imagery appears. [synthesis]
Religious or cultural sensitivity: toning can resemble chant, mantra or prayer, and Bernardi et al. relate its breathing pattern to chanted prayers and mantras. [source: Bernardi et al. 2017] Ask about the client's beliefs, and do not borrow sacred chants or syllables as clinical technique. [synthesis]
Children and young people: the sources do not cover toning with children. [not found] If you adapt it: get parental consent and the child's assent, use playful framing (animal or siren sounds), keep it short, and follow your usual safeguarding duties. [synthesis]

5.8 "Nothing is happening"

Some clients feel nothing. Check whether the breath is held or the sound is clipped. Try lengthening the exhale, lowering the pitch, or having the client place a hand where they feel vibration (chest, face). If toning still adds nothing after 2–3 tries, drop it and move to another method. Austin's principle that vocal work is not a recipe applies here. [source: Austin interview 2011; responses: synthesis]
