Tuning - Major Diatonic, Part 8

For a tuning to work well for us blues players we need to have the I7, IV7 and V7 Chord notes (individual) and chords (all at the same time) available to us as well as a Blues Scale on the I7 Chord. Having a Blues Scale available on the IV7 and V7 Chords are added bonus, but the I7 Chord has to be robust.

1st Position - C Harmonica played in the Key of C

I7 Chord (One-Seven Chord)
- C E G B-flat
- Found on all blow notes (C E G) and 3', 10"+ (B-flat) = Very Available
- The majority of the chord can be played as a chord (all at the same time) = Very Available

IV7 Chord (Four-Seven Chord)
- F A C E-flat
- Found on 1+, 2", 3", 4+, 5, 6, 7+. 8'+, 9, 10 = Available, but split between draws, blows and bends = Difficult
- The majority of the chord cannot be played as a chord... not more than two notes of the chord available at once = Not Very Available
- The IV7 Chord in 1st Position is a very difficult chord to play and most do not know how to find/use it.

V7 Chord (Five-Seven Chord)
- G B D F
- Found on all draw notes and 2", 3+, 6+ and 9+ = Very Available
- The majority of the chord can be played as a chord (all at the same time) = Very Available

So, as for chords, the I7 and V7, the most important of the three chords, are available... very promising. Tomorrow we'll look at the blues scales available to each chord.
