Piano key frequencies
This is a virtual piano with 88 keys tuned to A440, showing the frequencies, in cycles per second (Hz), of each note. This distribution of frequencies is known as equal temperament, i.e. each successive pitch is derived by multiplying the previous by the twelfth root of two. For other tuning schemes refer to Musical tuning.
