The pitch of a musical note is determined by its frequency in hertz. the p(t)=a sin (2pift) approximates the sound of a note with volume t seconds. for the purposes of the following problems, we will volume where a=1. within a major scale, the frequencies of the note maintain the first note to the third note have a frequency ratio of 4: 5 the the first to seventh a ratio of 8: 15, and the first to the below, you will see the graph of the standard pitch. a at 440hz in black, in grey as well as the eight note of an octave of the a major scale with give the equation, p(t), the function in and identify which pitch it is the note is and can be modeled by p(t)= find the equation, p(t), for c# and add its graph to the graph of
