What it teaches

Start on the piano's third and slide down, slowly, until the chord stops beating. That's the ring: hear it found.

Mi inside the chord. This time mi is in the middle: harder to hear

Slide down slowly. A hair at a time

Stop where it hums. The beating stops

What you sing

  1. Your hunt: start on mi where the piano has it, slide down slowly until the chord hums, and stay there. Headphones on.

Singing safely

Sing straight, not squeezed, at a medium-soft volume. Wear headphones: ringing needs them. Stop if anything tightens or hurts, and rest when hoarse.
