What it teaches

A lip trill is a "brr" like a motorboat: loose lips fluttering on easy breath. It's one of the gentlest ways to wake your voice up.

Loose lips. A fingertip at each corner of your mouth helps

Easy breath. Never forced, just a steady flow

Stop if it strains. Tightens, tickles or hurts: rest. Don't sing when hoarse or ill

What you sing

  1. Ride the roller coaster on one bubble: up, down, up again. Can't trill yet? Hum or slide on "oo" instead: the app follows whatever easy sound you make.
  2. One more bubble, then listen back.

Singing safely

Keep every sound quiet to medium and easy, never forced, and stop if anything tightens, tickles or hurts. Can't trill yet? A hum or an "oo" does the same job here.
