1)A note consists of a fundamental frequency and the multiples of that frequency called harmonics. Peak frequency means that one that contributes most to the note. Is the fundamental frequency always the peak frequency? Since the frequencies die out very quickly as the value of n increases, where n is the factor that multiples the fundamental, shouldn't the fundamental always have the highest peak?
2)Is the first frequency always the fundamental?
3)When looking up frequency tables, there are specific numbers given for each note eg C3 has 63.5 Hz approx. What does this refer to? The peak, the fundamental, or some other value altogether?
Thanks!
