| Notes and Their Frequencies |
|
For those of you who have wondered what the exact frequency of each note is, we provide the following chart. Remember, however, that the voice of the bass is in the mids, beginning with the first harmonic. The chart covers everything from Low A (for those who de-tune a whole step) to 24th fret F (for those with seven string basses).
