More in Two lines, one song

Two songs at once

Songs on the same chords, in the same time, often fit together. Singing two at once is a quodlibet, Latin for "whatever you please".

Row, Row, Row is yours. Twice through

Are You Sleeping above. Swung, so its bars line up with yours

Two tunes, one chord. Both rest on do

What you sing

  1. After a bar of the drone, sing Row, Row, Row twice through while the guide sings Are You Sleeping.

Challenge: The last verse

Two verses, two parts: the tune first, with a descant over you; then the descant yourself, over the tune.

Verse one. The tune, the guide's descant above

The last verse. Your descant, two lines long

Hold the end. Your last note rings over the home chord

What you sing

  1. Verse one: sing the tune while the guide sings a descant above you.
  2. The last verse: your descant over the tune, two lines, and hold the last note.

Singing safely

Sing at an easy volume, in the middle of your range. Stop if anything tightens, scratches or hurts, and rest your voice.
