78.95Mini-composition exercise

Write 24 bars where upper-voice motion generates most of the harmonic sophistication.

Requirements:

• at least one ii–V–I with three-note RH voicings
• one common tone surviving three harmonies
• one A→A♭→G top line
• one E→E♭→D line
• one G7alt upper structure resolving by three individually planned voices
• one sus→dominant→altered progression
• one tritone substitution where most RH notes remain
• one borrowed iv with a smooth chromatic inner line
• one chromatically planed upper structure
• one half-step modulation voiced mostly by semitone motion
• one deliberate large melodic leap after several bars of minimal motion

The listener should hear rich harmony, but the pianist should feel surprisingly little physical motion.
