49.89Mini-composition exercise

Write 30 bars—five large six-bar units if you like—in C Dorian/Minor.

Requirements:

• main meter 6/4
• 3+3 bass ostinato
• 2+2+2 RH section
• one four-beat repeating motif
• one five-beat repeating motif
• one brief 4/4 section using the same four-beat motif
• one return to 6/4
• one functional G7♭9→Cm cadence
• one rhythmic resolution without harmonic resolution
• one simultaneous harmonic/rhythmic resolution

Keep harmonic roots to roughly three or four.

The goal is not harmonic abundance.

It is temporal architecture.
