A bugle is simply a coiled length of pipe, without slides or valves. One plays different notes on a bugle by buzzing ones lips at different frequencies.
a. How does this change the pitch(frequency) of the sound the bugle makes?
b. The bugle can play only certain pitches and not others (for example think of the piece "Taps" which is entirely cunstructed of only four different pitches). What are these allowed pitches, and why are other pitches impossible.
c. Imagine that a certain bugle plays in C, so that the pitches in "Taps" are low G (196 Hz), middle C (261 Hz), E (329 Hz), and G (392 Hz). How long would this bugle be if uncoiled?
