How to Play B on Chromatic Harmonica
B is the draw note on hole 4. It completes the natural notes of the lower octave (C D E F G A B) on a C chromatic harmonica. With B in place, you can play a full C major scale.
What you will learn
- How to isolate hole 4 cleanly
- How to move from hole 3 to hole 4
- How to play a complete lower-octave scale
Step 1: Find hole 4
From hole 3, slide the harmonica one more hole to the right. Draw gently. You should hear B — a step above A.
Check that you are only covering hole 4. If B sounds thick or chordy, narrow your embouchure.
Hover a control to see what it does.
Find a clear B tone
Use this drill to settle the B sound and practice moving from hole 3 to hole 4.
Step 2: Connect A to B across holes
Moving from A (draw hole 3) to B (draw hole 4) means you keep drawing while shifting one hole to the right. This is a new kind of movement — same breath, different hole.
Try to make the slide smooth so there is no gap between A and B.
Hover a control to see what it does.

Common mistakes
- Stopping the draw when moving to hole 4
- Overshooting and landing on hole 5
- Tensing the lips during the slide

You completed the lower octave
With C, D, E, F, G, A, and B, you can now play a full C major scale on holes 1–4 of your chromatic harmonica. Try playing the scale slowly from C up to B and back down.
