Workshop 44 mini-test

1. How is a basic 6/8 bar grouped?

2. How can the same six eighth notes produce a 3/4-like layer?

3. Which subdivisions are accented in 3+3?

4. Which in 2+2+2?

5. What is a hemiola?

6. Why is 3-against-2 not necessarily two tempos?

7. What happens when a two-eighth motif repeats over a 6/8 bass?

8. Why must the subdivision speed stay constant when changing perceived grouping?

9. How is this different from additive 9/8?

10. What is the deepest lesson of Workshop 44?

Answers
  1. 3+3: two groups of three eighth notes.
  2. Accent the same six eighth notes as 2+2+2, creating three equal two-eighth groups.
  3. 1 and 4.
  4. 1, 3, and 5.
  5. A temporary reinterpretation of an established compound/triple grouping—commonly 3+3 becoming 2+2+2 or vice versa—without changing the underlying subdivision.
  6. Both rhythmic layers occupy the same total duration and use the same underlying subdivision; they organize that duration into two versus three larger pulses.
  7. It naturally creates the three-pulse layer against the bass's two large 6/8 pulses.
  8. Because the musical effect comes from changing grouping, not changing tempo.
  9. Additive 9/8 builds one asymmetric bar from unequal groups such as 2+2+2+3; 3-against-2 in 6/8 overlays two different symmetrical organizations of the same six subdivisions.
  10. Rhythmic freedom comes from being able to hear more than one valid organization of the same pulse without losing the underlying time.

The central lesson of Workshop 44 is:

The deepest rhythmic independence is not playing faster or counting stranger numbers—it is being able to hear “two” and “three” at the same time and feel that both are true.
