A longer loop

Four bars now, four notes: do, low la, re, low so. A loop that moves through four chords.

The last note stops early. That's your breath, and the loop's seam

Each note twice. Then a rest

Headphones on. Through a speaker, your loops rest while you sing

What you sing

  1. Find each note of the four-bar bass: each waits until you're on it.
  2. Hear each loop come round, then choose.
  3. The four-bar bass, twice round. Stop the last note early, before the loop comes round. Easy volume, light, never pressed; stop if anything tightens or hurts.
Try one round

Challenge: Your first loop

Your first loop, kept for the end of the course: the four-bar bass once, then the gap part over it, with a rest in the middle.

Kept for later. The course's last lesson plays it beside your new bass

Sing, rest, back in. After one round of listening

Headphones on. Through a speaker, your loops rest while you sing

What you sing

  1. The four-bar bass, once round. Easy volume, light, never pressed; stop if anything tightens or hurts.
  2. Listen once round, fill the gaps once round, rest a round, then come back in: mi, then fa, then re.

Singing safely

Headphones on. An easy volume, the middle of your voice; the bass sung lightly, never pressed. Stop if anything tightens or hurts.
