A Listening Map of 50 Piano Works · Article 38
Prokofiev’s Toccata resembles a machine gradually exposing its parts: repeated-note axle, chromatic gears, chordal pistons and expanding register. It sounds nearly uncontrolled, yet exact addition and retrieval govern the structure.
Disassemble the machine
| Part | Function |
|---|---|
| Repeated note | Maintains engine speed |
| Chromatic motion | Continuously displaces the mechanical surface |
| Chordal impact | Marks structural joints rather than accenting everywhere |
| Register expansion | Turns a tabletop device into an entire factory |
Mechanical does not mean inflexible
Long phrase and direction exist above the pulse. Equal tension in every bar produces only noise; oppression comes from progressive addition and diminishing space.
Hear moments of jamming
Brief pauses, rhythmic displacement or sudden changes of register resemble gears failing to mesh. They make continuous movement dangerous rather than mistaken.
- Hear whether pulse changes.
- Count structural chord impacts.
- Follow register expanding outwards.

Poon’s live video makes repeated motion visible. Resist focusing on hand speed and first test whether the machine’s larger beat remains stable.
