90.113Mini-composition exercise

Write a 32-bar étude built from one primary rhythmic motif and two related transformations.

Requirements:

• one exact statement of the primary motif in first 2 bars
• one displaced version
• one augmented version
• one diminished version
• one fragmented version
• one retrograde-duration version
• one appearance in melody
• one appearance in accompaniment
• one appearance in bass
• one appearance crossing a chord change
• one appearance crossing a bar line
• one 3- or 5-unit cycle against 4/4
• at least 4 bars where motif is completely absent
• one metric realignment functioning as a structural cadence
• global climax must combine harmonic arrival with rhythmic realignment
• coda must recall the original rhythm in a slower/sparser form

The listener should be able to feel that the entire study grew from one rhythmic seed.
