MIDI Notes and Frequencies |
The following chart shows the musical pitch and frequency associated with each MIDI note.
A5 is 440 Hz, and middle C is C5 at 261.63 Hz. These values can differ — often by one octave — from values used by other manufacturers. Some MIDI sequencers and sound modules use C-1 as MIDI key 0, which then makes middle C C4.
The following frequencies are based on equal temperament tuning.
