Unit 1 · Swing and settle

The easy long note

Sigh into an "ah" and hold it over a drone at a medium volume, jaw still, then an "oo" a step higher: the steady, free note that vibrato grows from. Free.

What it teaches

A vibrato grows from steady breath and a free throat. It starts with an easy note.

Sigh into "ah". Like a relieved sigh, then hold it

Medium volume. Not quiet and breathy, never loud

Check your jaw. Rest a fingertip on your chin. It should stay still

What you sing

  1. Sigh into "ah" and hold it, easy and steady, over the drone.
  2. Now "oo", a step higher, just as easy: sigh into it and hold.

Singing safely

Never force a wave or shake it from your jaw or throat: vibrato grows by itself from an easy note, sung softly.
