Ear Training for Piano Tuners – Tuning A4 – Lesson 1

Lesson 1 - Tuning A4


When tuning aurally, we use a reference for A440. We usually use a tuning fork or an electronic sound source. (From now on, I will always refer to the fork as the A440 reference, but you could also use an electronic source.)

Listening to A4 and the fork together is one way to tune A4 to the fork.

The A4 above is out of tune with the fork. You should hear a beat which indicates it is out of tune. If you had trouble, listen to them again, but this time, the A4 will be filtered so that you will only hear the beat and not all the other partials present in the sound.

You should play the unfiltered version above and try to hear this beat within that sound.

Aural piano tuners work to develop their ear's ability to filter out unwanted frequencies so they can clearly hear the beats produced by out of tune intervals.

For example, listen to this recording of the same out of tune A4 and the fork, but this time, the waveform will be filtered around E6; the third partial of the fork and A4.

To really test your ear, play the unfiltered A4/Fork waveform two buttons above. An experienced aural piano tuner can easily here this fast beat in the unfiltered sound.
