  1. Listen to teacher and student selected songs for changes in the texture of chordal rhythm roles, variation in the bass and chordal parts, and contrast between sections.


  1. Write three chord progressions, identify the letter name and quality of each chord, and invert them to create smooth voice leading. 

  2. Write a bass line with octave jumps and leading tones for each section. 

  3. Create at least one chord part for each section using either pads and punches, ostinato, and/or riff rhythmic roles. CHECK STUDENT ANSWERS 

  4. Record four measures of the bass and chordal parts as separate tracks in Soundtrap. 

  5. Quantize the performances to the correct subdivision and trim the releases of each note to the correct count. 

  6. Loop and copy/paste the phrases to match the phrase structure of the 6.2 Pop Song Organizer →
