Workshop 56 mini-test

1. Why is a two-beat first chorus useful?

2. What changes when bass moves from two-beat to four-beat walking while tempo remains constant?

3. Why should RH voicings often become thinner when LH starts walking?

4. What is the basic intensity ladder developed here?

5. What is a shout chorus conceptually?

6. Why does modulation work especially well after several repeated choruses?

7. What are the two main modulation strategies discussed?

8. Why is C6 often more stylistically appropriate than Cmaj7 as a classic-swing ending?

9. What is an intensity map?

10. What is the deepest lesson of Workshop 56?

Answers
  1. It clearly establishes the tune while deliberately leaving room for later growth in bass density, texture, register, harmony, and orchestration.
  2. Perceived drive increases because bass activity doubles from two structural pulses to four quarter-note events, even though BPM has not changed.
  3. Walking bass already contributes substantial rhythmic and harmonic information; thinner RH shells preserve clarity and avoid overcrowding.
  4. Two-beat → walking → octaves → block chords → shout → sparse release, with variations possible.
  5. The arrangement's high-energy ensemble-style climax, typically built from a clear repeated riff, thicker texture, rhythmic coordination, register, and repetition rather than merely faster melodic lines.
  6. The listener already knows the melody and key environment, so hearing the same material suddenly higher creates immediate renewal and escalation.
  7. Prepared modulation through the new key's dominant, and direct modulation with an immediate key change.
  8. The added 6th tends to produce a warmer, more settled vintage swing sonority, whereas maj7 gives a more modern/floating tension.
  9. A planned outline of relative energy levels across the performance, using dimensions such as bass activity, texture, register, rhythm, harmony, and dynamics.
  10. A successful repeated-chorus arrangement is a controlled journey of energy: each chorus needs a reason to exist beyond simply playing the tune again.

The central lesson of Workshop 56 is:

When the melody repeats, the listener does not need more melody—they need a new reason to hear it again.
