A three-minute warm-up

What you sing

  1. A trill hill. Can't trill yet? Hum or slide on "oo" instead: the app follows whatever easy sound you make.
  2. An "ng" siren.
  3. A hummed line.

Challenge: Your warm-up

Your first roller coaster beside today's, then a line sung on a warmed-up voice.

One bubble. Up, down, up again

Then sing. Easy, at talking volume; stop if anything tightens or hurts

What you sing

  1. The roller coaster again, on one bubble. Can't trill yet? Hum or slide on "oo" instead: the app follows whatever easy sound you make.
  2. A line on "la", heard then sung.

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.
