Answers
  1. Their five-note structure is easy to hear and finger, tends to avoid some of the strongest functional clashes, and concentrates characteristic chord extensions into a compact vocabulary.
  2. C-D-E-G-A over F = 5,13,maj7,9,3, giving a rich F-major/maj13-type color.
  3. Over A it gives ♭3,11,5,♭7,root, producing an Am11-like minor environment.
  4. D-E-F♯-A-B over C gives 9,3,♯11,13,maj7, concentrating nearly every characteristic C-Lydian color while omitting less interesting root/5th duplication.
  5. B♭-D♭-E♭-F-A♭ provides ♯9,♭5/♯11,♭13,♭7,♭9 over G; with the G7 3rd supplied separately, it creates a powerful altered-dominant vocabulary.
  6. B♭-C-D-F-G over C = ♭7,root,9,11,5, giving a C9sus-type environment.
  7. Instead of shifting one motif/chord shape outside by a semitone, you can shift the entire pentatonic vocabulary temporarily and then return; the stable internal shape makes the outside move coherent.
  8. Complete sequential runs reveal the scale mechanically; fragments, leaps, repetitions, motifs, and rests turn the collection into melodic vocabulary.
  9. They are different organizational views of overlapping pitch material: the full scale gives the field, pentatonics concentrate color, triad pairs provide familiar substructures, quartal voicings reorganize intervals, and upper structures relate familiar shapes to a bass/core chord.
  10. A pentatonic is not merely a beginner's five-note scale. In advanced playing it becomes a portable harmonic object whose meaning is determined by the bass, the chord beneath it, and the destination of the line.

The central lesson of Workshop 64 is:

The more harmony you understand, the less you need to treat every note as an independent decision. Choose a five-note world with the right gravity, and then make music inside it.
