Altered Scale (April 2015)
The altered scale notes are derived from the 7th mode of the Harmonic Minor Scale.
When playing in the key of C, the C7#9 would be suitable as a backing chord.
Guitarmodes students have the foundation to play the harmonic minor scale, it's modes and chord structure in any inversion across the fretboard.
If a student does not know the scale, A 1 minute description is all they need to achieve this knowledge.
