1. An open-open cylindrical instrument is playing its lowest note (all the toneholes are closed). The player then opens a register hole without changing the fingering. a. what is the interval between these two notes? b. sketch the first normal pressure modes of the n=1 note and the n=2 note on the lines below. The line represents the effective length of the instrument in that fingering. 2. A bassoon has an effective length of 0.982 m in a particular fingering and is playing in its lowest register. a. find the frequency and note name it is playing. b. give the frequencies and note names of the next two harmonics present in the sound
