General Questions:

1. How many eighth notes do you need to fill up a measure in 11 - 4 time? in 7 - 8 time?

2. In 5 - 4 time, how many beats does a triple-dotted quarter note get? How many beats does it get in 3 - 2 time?

3. What is the sum of an infinite geometric series that begins with 3 and has a ratio of -2/3? Write out the first five terms of the corresponding geometric sequence (the terms being summed).

4. Suppose you come across a measure of music that asks you to play a polyrhythm of 10 against 6. How many pulses would you subdivide the measure into in order to see precisely where the pulse of each rhythmic pattern goes?

5. Give an example of two integers a and b such that the lcm(a,b) = b. What must the gcd(a,b) be equal to for this to be true?

6. Is it possible for the lcm(m,n) to be n^2? If so, find conditions on m and n that always yield this result. If not, explain why not.

7. Find the lcm(2,5,10), lcm(3,5,10), and lcm(4,5,10).

21. How many keys are there on the modern piano keyboard? Roughly how many octaves fit into the piano keyboard?

22. If two scales are considered identical when they contain the same overall set of notes, how many different whole tone scales are there? How many different major scales are there? Explain.
