Written quiz

On a separate sheet of paper, answer the following:
Suppose

Pattern A = ddzdzdz
Pattern B = zzdzdzd
Pattern C = dzzz
1. What is the total length of AABA ?
2. What is the total length of (AC)2 ?
3. What is the total length of ((AC)2 B)2 ?
4. Why is the following not a legitimate composition?
1. Drum 1:  AABA
Drum 2:  (AC)2
5. Explain how you could fix the composition in Question 4 to make it follow the rule.
6. Extra Credit:  Which of the following patterns are complementary:  A and B, A and C, or B and C?

Abcdrums exercises

Open ABCDRUMS.

Refer to the handout on polyrhythms.

1. Assign Patterns A-F to each of the divisions of a measure of 12 beats.  Then choose a drum for each pattern and make it play its pattern 4 times.  When you are done, save the MIDI file and have me check it.
2. Now find all the divisions of a measure of 16 beats, clear your abcdrums screen, and follow the same directions as Exercise 1.

Polyrhythmic patterns.  You can create more complex polyrhythms by using patterns of different lengths and playing them simultaneously.  For example,

Pattern A:  dzzd
Pattern B:  dzd

Drum 1:  A3
Drum 2:  B4

Since A3 is the same length as B4, this composition satisfies the rule.

1. Try the above patterns, but make the full cycle of 12 beats repeat 4 times for both drums.  Have me check your MIDI file
2. Choose your own patterns, each  of different lengths, and make a polyrhythmic composition for at least 2 drums that follows the rule.  Have me check your MIDI file.
