More in Steer the wave

What it teaches

A wave you steer is the gym for vibrato: slow and even first, then a little quicker. Tiny slurs between two notes. Jaw and belly still.

Rest a fingertip on your chin. It shouldn't move

Slow and even. Every wave the same size

Quicker, never harder. Smaller as it speeds up

What you sing

  1. Follow the ribbon: 2 a second, then 3, then 4.
  2. Again, with an extra rung at 5 a second if you like. Stop whenever it feels tight.

Singing safely

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