Note Frequency Charts

A chart of the guitar fingerboard up to the 15th fret, in staff notation
(one stave for each string), with letter names for each note and the frequency
of the corresponding tempered pitch. (Since the guitar is an approximately
tempered instrument and each instrument is unique, the actual pitches will
vary slightly from one guitar to the next.) The guitar's range in hz. is from

82.4 (Low E string) up to about 2600 for the highest harmonics.

The same chart is shown for the piano keyboard lower on the page.
