When two notes are played at once where their frequency spectra share a high-amplitude frequency, these two notes sound pleasant when played together. If the two notes have frequency spectra where all non-negligible frequencies are multiples of the lowest frequency (as is the case with most methods of sound production, including the human voice, most instruments, and square/saw/triangle waves) they will sound concordant when they have frequencies a and b where b/a is rational. In this case, the frequency they share lies at [[Lcm|LCM]](a, b).<references /> | When two notes are played at once where their frequency spectra share a high-amplitude frequency, these two notes sound pleasant when played together.
