The following table presents the frequencies of all notes in ten octaves to a thousandth of a hertz. Luckily our good friend Wikipedia gives us a little algorithm to do just this.

A number of calculations useful to builders of stringed musical instruments require the frequency or wavelength of a note as input data. Let's turn our browser into a mini synthesizer.
