Need a note frequency chart? This reference lists every musical note from C0 to B8 in Hz, with MIDI note numbers and wavelengths. Use the Hz to note converter to identify a pitch, and adjust the A4 reference if you tune to a different standard. Useful for music students, teachers, and anyone studying music theory or ear training. Save this pin for your next lesson plan.

f = 440 × 2^((n−69)/12). That's it. Plug in the MIDI note number, get the frequency in hertz. No chart lookup needed. This post breaks down each piece of the formula and shows how equal temperament locks every semitone to the same ratio — 1.05946 — twelve times over.


Use this music note frequency chart to quickly find the Hz frequency of common musical notes from C4 to C5. See C4 (Middle C), A4 (440 Hz), and other note frequencies in 12-tone equal temperament, then explore the complete chart for more octaves.

A hypothetical unknown steady pure tone makes 4 Hz beats with a 256 Hz reference, so its frequency could be 252 or 260 Hz. Increase only the reference to 258 Hz while keeping the unknown fixed: the candidates predict 6 or 2 Hz beats. Observing 2 Hz selects 260 Hz. Use the absolute-difference formula, check both observations and distinguish beat frequency from either tone’s frequency. Explore the NUM8ERS Physics Formula Guide.
