88.103Mini-composition exercise

Write a 40-bar piece organized around harmonic memory.

Requirements:

• establish one clear tonic early
• introduce one distinctive non-diatonic chord/progression within first 8 bars
• do not repeat it for at least 12 bars
• return it later as a structural callback
• one cadence must be denied and resolved much later
• one chord must change functional status at least twice
• one pitch that begins as chromatic tension must later become a stable chord tone
• one future tonic must be foreshadowed before modulation
• one expected chord must be omitted after its pattern has been established
• one dissonant sonority must become normalized through repetition
• one later consonant sonority must derive impact from removal of that tension
• final harmony must retrospectively clarify an ambiguity from the opening

The piece should reward the listener for remembering earlier events.
