4.4 lesson plan // chordal rhythm: ostinatos and riffs
Play teacher and student selected music and identify when chordal instruments are playing ostinatos and riffs.
Write ostinato and riff rhythms as a class.
Write a chord progression, indicate the letter name and quality of the chords, and invert the triads to maintain smooth voice leading.
Create a rhythm for the chordal part. The rhythm should repeat every measure for an ostinato and should follow a four measure repetition structure for a riff. CHECK STUDENT ANSWERS
