Swing your voice

Start vibrato with tiny slurs on a soft hum, a slow swing, then quicker and smaller, jaw and belly still, then settle into one easy long note. Free, gently.

More in Swing and settle

What it teaches

You're about to see your voice draw a wave. Keep it soft, in the middle of your voice, and stop if anything tightens or hurts.

Hum, softly. "Mm" or "oo", at a medium volume

Swing up and down. Tiny slurs, jaw and belly still

Then settle. One easy long note, nothing steered

What you sing

  1. Follow the ribbon on a soft hum: a slow swing, then quicker and smaller.
  2. Now one easy long hum. Nothing to steer: let it be.

Singing safely

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