7 Positions in One Scale - Part 5 (12th Position)

The fourth of the seven positions starts on the 4th Scale Degree of the Major Scale and is called 12th Position... this is playing in the key F on the C Harmonica. The Mode created is called the Lydian Mode.

The notes are as follows:
F G A B C D E F (same notes as the C Major Scale, just starting from F)

Intervals:
Whole | Whole | Whole | Half | Whole | Whole | Half

Scale Degrees (Relative to its equivalent Major Scale):
1 2 3 #4 5 6 7 8

Full Scale:
1+ 1 2+ 2"
2" 2 3" 3 4+ 4 5+ 5
5 6+ 6 7 7+ 8 8+ 9
9 9+ 10 10'+ 10+

Being only one bend away from the F Major Scale (B-flat = 3' and 6OB), it's a commonly-experimented-with mode, especially by players that utilize overbends. Dennis Gruenling, Chris Michalek and Jason Ricci cover this position in their interviews at BluesHarmonica.com.
