Notes by category — C harmonica, 1st position

Anchor— Chord tones

CEG

In 1st position on a C harmonica, your home key is C major and the I chord is C-E-G. C major is the harmonica community's most common key -- nearly all lesson material is written for it. The C, E, and G are these chord tones -- the gravitational center of any melody in C major. Phrases that resolve onto C, E, or G feel settled, especially the root C, which sits at blow 1, blow 4, and blow 7.

Support— Other scale tones

DFAB

The D, F, A, and B fill out the rest of the C major scale on the C harmonica. The 7 (B) is the leading tone -- it pulls strongly up to the root C, especially on a strong beat -- but in folk, country, and pop contexts you can rest on it briefly without losing the sound. The 4 (F) is a subdominant target, while the 2 (D) and 6 (A) act as smooth connectors between the chord tones.
