Table of Musical Notes and Their Frequencies and Wavelengths

A number of calculations useful to builders of stringed musical instruments require the frequency or wavelength of a note as input data. The following table presents the frequencies of all notes in ten octaves to a thousandth of a hertz. Octaves are presented in the Scientific Pitch Notation format, also commonly referred to as American Pitch Notation and International Pitch Notation.
