Fourier series (music)
The ideas of Fourier series have interesting application in music, for example, in illuminating the differences in pitch between musical instruments and in the construction of music synthesizers. The frequency spectrum of a musical instrument playing a particular note varies with the instrument and with the way that it is played. Some instruments {like the flute or the violin) exhibit a fundamental frequency and its harmonics in varying amplitudes and phase, and others (like the cymbal or the drum) do not.
