93.124Mini-composition exercise

Write a 40-bar/approximately 3-minute solo-piano étude whose form is organized by changes in temporal behavior.

Requirements:

• establish a clear initial tempo
• use both half-time/double-time illusion and at least one actual tempo change
• one genuine gradual ritardando
• one accelerando with a clearly stabilized destination tempo
• one fermata on an unresolved harmony
• one fermata or prolonged silence after resolution
• one measured silence
• one free caesura
• one section with pulse-preserving rubato
• one section of genuinely free time
• one re-entry into strict tempo via pickup, bass pattern, or subdivision
• one tempo transition using metric-modulation logic
• one harmonic arrival that occurs before metric resolution
• one metric arrival that occurs before harmonic resolution
• final section must either dissolve from pulse into free time or crystallize from free time into pulse

The piece should make the listener feel that:

time itself has form.
