Repeat phrases of a moderate length and complexity in a variety of styles

Develop further call-and-response or echo exercises, perhaps using more challenging keys and a wider variety of styles and forms, e.g. waltz, Latin-American rhythms, riffs.

Sing scales in canon, e.g. one learner starts, the next begins two notes later, the third a further two notes on, thus producing a sequence of chords. Discuss whether the chords are major, minor, diminished, etc.

Sing arpeggios in canon, learners starting on successive notes. Discuss whether the resulting chords are in root position, first inversion, etc.

Sing simple songs in canon, with either the teacher or other members of the group leading. The second group repeats the part sung by the first group.

Continue the activity in pairs, with the second singer decorating the line or improvising answering phrases in the style of the first. Whole pieces can be built up in this manner.
