Chord Tones

When playing in 2nd Position on a C Harmonica you and the band are playing in the key of G. Referencing the 12 Bar Blues Chart on the last page of most of your PDF lesson pages, you'll see that we use a I7, IV7 and V7 Chord. Each chord represents what the band is playing under you when you solo.

In the key of G our scale is: G A B C D E F# G.

To build a I7 chord we start with the first note (G), thus the I (roman numeral one) designation, and you skip notes to create the chord... which equals G (skip A), B (skip C), D (skip E) and F# lowered down a half step (to make it bluesy) to equal F.

Our I7 Chord = G B D F

When the band is on the I7 Chord (the first four measures) if you play any of these notes you will match. Referencing the C Harmonica Note Layout (found as a PDF in he Support Material of the "Understanding Positions Lesson") these are the hole numbers that match:

I7 Chord = 1, 2", 2, 3, 4, 5, 6+, 7, 8, 9, 9+

Grab a jam track from one of our study songs and give this a try.

This seems pretty simple, and will be, but it will be a primer for understanding ideas on the IV7 and V7 Chords, and ultimately 3rd Position playing.

Give it a try!
