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

In North Truro the women and girls may sit at their doors, and see where their husbands and brothers are harvesting their mackerel fifteen or twenty miles off, on the sea, with hundreds of white harvest wagons, just as in the country the farmers’ wives sometimes see their husbands working in a distant hillside field. But the sound of no dinner-horn can reach the fisher’s ear.” “The good husband finds method as efficient in the packing of fire-wood in a shed, or in the harvesting of fruits in the cellar, as in Peninsular campaigns or the files of the Department of State.” |
