The Acoustic Scale
Now, here we a very special mode/scale. If you´ve done
your homework on the other scales examined on these pages
you´ll see that it´s basically a combination of the
Mixolydian and Aeolian
The great Hungarian composer Béla Bartok (1881-1945) discovered
this scale in Romanian folk music and many people refer to it as the "Bartok-scale".
The scale´s root is here placed in E, followed by F#, G#, A, B, C and D.
Play a sequence of an Eadd9-chord (E, G#, B and F#) and an Eadd9+5sus4-chord
(E, C, A and F#) and try the scale out over it. Worth checking out.
