What are the notes on a harmonica?

A 10-hole diatonic harmonica has two notes per hole: a blow note (exhale) and a draw note (inhale). On a C harmonica, hole 4 blow is C and hole 4 draw is D. The full layout repeats the same blow-draw pattern, transposed, in every key.

How many notes does a harmonica have?

10 holes times 2 directions gives 20 note slots, but several holes share a pitch an octave apart, so a diatonic harmonica plays 19 distinct notes before you add bends or overblows.

Is there a printable harmonica notes chart?

Yes, the tables on this page cover C, G, A, D, and E harmonicas and can be copied into a note-taking app or printed. The layout is identical for every key, only the note names shift.

Do the notes change if I buy a different key of harmonica?

The pattern stays identical (blow is always the root-third-fifth, draw is always the second-fifth-seventh), but every note name shifts up or down with the key. A hole 4 blow on a G harmonica is G, not C.

What is the difference between a notes chart and a scale chart?

A notes chart lists what pitch comes out of every hole in both directions. A scale chart picks out which of those holes, in order, form a specific scale like major or blues - it is a subset of the notes chart, read in a different order.
