Modal Scale Interpretations Pt. 1
This series of posts shows how the modal scales can be interpreted into different scales. This particular part talks about harmonic modal scales which is essentially the harmonic minor key being played from different starting notes which are used in the same way as modal scales. For example, A harmonic minor is: A, B, C, D, E, F, G#, A. A harmonic ionian (major) scale - for example - would be the same but starting on C (C, D, E, F, G#, A, B, C).

A harmonic minor scale played on 1 string (with the root note starting on the open string) would be played like this:
0-2-3-5-7-8-11-12
The interval degrees played would be:
1, 2, b3, 4, 5, b6, 7, 8
These 2 ways of writing the scale will be how I will format the examples.

Harmonic Locrian -
0-1-3-5-6-9-10-12 - 1,b2,b3,4,b5,6,b7,8

Harmonic Ionian (major) -
0-2-4-5-8-9-11-12 - 1,2,3,4,#5,6,7,8

Harmonic Dorian -
0-2-3-6-7-9-10-12 - 1,2,b3,#4,5,6,b7,8

Harmonic Phrygian -
0-1-4-5-7-8-10-12 - 1,b2,3,4,5,b6,b7,8

Harmonic Lydian -
0-3-4-6-7-9-11-12 - 1,#2,3,#4,5,6,7,8

Harmonic Mixolydian -
(1-2-4-5-7-9-10-13)

The Harmonic Mixolydian semitone intervals can all be lowered by one to make the proper scale:
0-1-3-4-6-8-9-12 - 1,b2,b3,b4,b5,b6,bb7,8

These scales are not officially used but I figured them out and occasionally use them along with the set of scales if the next parts (although some of these scales have already been created and been given different names unrelated to modal scales).
