Blues Scale

This page shows how the blues scale can be played in three different keys on a single harmonica. Specifically, using a C harp I will provide harmonica tablature to play the blues scale in C (first position), G (second position), and D (third position). But first let's look at what notes are available on the C harmonica. The notes in red indicate the use of an over blow or over draw.
