MIDI Note Numbers

The MIDI note numbers 0 to 127 map to musical notes as shown in the following tables. Note that although most manufacturers label this range as C-2 to G8, with middle C being C3 (as I have here), you may come across some manuals that describe this range as C-1 to G9 (with middle C being C4).

The first table lists the MIDI note numbers, in hexadecimal (base 16).

Middle C is highlighted.
