Preface: A Passage of Scripture and a Question That Can Be Tested

The voice singers find hardest to hear is often their own. On a recording it sounds like a stranger; on stage it drifts off pitch without their noticing; under pressure the throat tightens and the singer pushes harder, chasing a sound that the audience will never hear the way the singer does. Over years of teaching singing, the author drew on the passage of the Śūraṅgama Sūtra in which Avalokiteśvara attains perfect penetration through the ear, and developed it into a listening practice he calls the Ergen Yuantong method.

The method has three stages, and this book follows them.

1. Acoustic decoupling. A singer hears their own voice by two routes at once: through the air, as everyone else hears it, and through the bones of the skull, which no one else hears. The first stage separates the two and stops the habit of squeezing the muscles around the larynx to make the inner sound match an outer sound the singer cannot actually hear.
2. Turning the hearing inward (fan wen). Attention is moved from controlling the movement of the voice (motor output) to listening to the sound and to the sensations it makes in the head (sensory input). The brain already runs a loop that compares what it intends with what it hears; this stage gives that loop room to work.
3. Phonating from the zero point (wen zixing, hearing one’s own nature). Before a note begins, the singer establishes it internally as a steady inner pitch, then lets breath and vocal folds meet that inner reference. The sutra’s phrase for the first step of Avalokiteśvara’s practice, “at first, within hearing, I entered the stream and forgot its objects”, is the image for this stage.

This book asks two kinds of question about the method.

First, what does the scripture actually say? The book quotes the text, gives the edition, summarises the scholarly debate about where the sutra came from, and keeps the author’s reading separate from the text itself.

Second, what might each stage correspond to in the body, and can that be tested? Auditory and voice science already know a good deal. We hear our own voice by two routes; the brain turns down the loudness of our own voice and keeps correcting our pitch without our noticing; the amplifier in the inner ear is under the brain’s control, and attention can change it; the vocal tract is a resonator whose behaviour can be calculated. These are published, checkable findings, and the book gives the formulas and the code. Whether the Ergen Yuantong method works through these mechanisms, or makes singers sing more accurately, there is at present no evidence. The book states the method as a hypothesis and sets out an experiment that could prove it wrong.
