Sound Files
The following audio files play various intervals. In each case the first note played is middle C. The next note is sharper than C by the assigned value in cents. Finally, the two notes are played simultaneously.
Note that the JND for pitch difference is 5-6 cents. Played separately, the notes may not show an audible difference, but when they are played together, beating may be heard (for example if middle C and a note 10 cents higher are played). At any particular instant, the two waveforms reinforce or cancel each other more or less, depending on their instantaneous phase relationship. A piano tuner may verify tuning accuracy by timing the beats when two strings are sounded at once.
Play middle C & 1 cent above, beat frequency = .16 Hz
Play middle C & 10.06 cents above, beat frequency = 1.53 Hz
Play middle C & 25 cents above, beat frequency = 3.81 Hz
