C or Do is the first note of the C major scale, the third note of the A minor scale (the relative minor of C major), and the fourth note (G, A, B, C) of the Guidonian hand, commonly pitched around 261.63 Hz.

The lowest C on the keyboard (the third white note from the end) is called C1. From there, each C to the right increases by one, so next we have C2, then C3. Then comes middle C, or C4 (those two names are interchangeable). Then C5, C6, C7, and finally the very last note on the keyboard, C8, all the way on the right:

2023年2月12日 · Some programs will say middle C is C3, while others can say it is C5. The software MaxMSP defines middle C as C3, while Apple’s Garageband defines middle C as C3. The main point is middle C (standard C4) will always be note number 60.

The American system of octave notation, for instance, stamps Middle C as C4. Meanwhile, the International system, employed extensively across various platforms, proclaims it as C3. Even Yamaha, consistently coloring outside the lines, devised an alternative system where Middle C straddles both identification as C3 and C4.
