Workshop 72 mini-test

1. Why is register a form of orchestration?

2. Why can leaving the middle register empty be useful?

3. What is the difference between a melody as solo horn and as horn section?

4. Why is octave doubling often useful before full block harmony?

5. What does texture rotation mean?

6. Why is role rotation better than simply accumulating more layers?

7. How can articulation make the same chord resemble different instruments?

8. Why should the highest register often be reserved?

9. Why can three widely spaced notes sound larger than six close notes?

10. What is the deepest lesson of Workshop 72?

Answers
  1. Because the same pitch material has radically different weight, brightness, prominence, and implied instrumental role depending on where it sits on the keyboard.
  2. Empty register creates separation and clarity between bass and melody, allowing the piano to sound spacious rather than continuously dense.
  3. A solo-horn melody is primarily a single projected line; turning it into octaves, thirds/sixths, or block/drop-2 harmony makes the melody feel like an ensemble section playing together.
  4. Octaves strengthen projection and register without introducing much additional harmonic density, making them an excellent intermediate intensity level between single line and full blocks.
  5. Changing which combinations of bass, melody, chords, countermelody, octaves, blocks, ostinatos, and pads are active from section to section.
  6. Accumulation eventually overloads the texture and leaves no headroom; role rotation creates contrast and development while keeping the total amount of information manageable.
  7. Short accented attacks can suggest brass/percussion, sustained legato voicings can suggest strings/organ, and short syncopated middle-register voicings can suggest guitar/comping, even with identical pitches.
  8. Because higher register is one of the easiest ways to create climax, brightness, or lightness; constant use removes that reserve.
  9. Wide spacing occupies more perceived sonic space and separates roles clearly, while many close middle-register notes can blend into a dense, smaller-feeling cluster.
  10. Solo-piano orchestration is the art of deciding which musical roles exist, where they live on the keyboard, and when each one enters or disappears.

The central lesson of Workshop 72 is:

To make two hands sound like an ensemble, do not try to play the whole ensemble at once. Let the imagined instruments take turns speaking.
