The Overtone Scale/Lydian dominant
The name Overtone scale refers to the many natural overtones/harmonics you can
find in, for example, the guitar.
Take the low e-string and pick harmonics with a finger of your choice on the left hand
gently, almost above the string (donŽt push down the string on the fretboard)
and youŽll see that an E Overtone scale pops up.
Compare it to the Lydian scale. The only tone that differs
to two is the seventh, which in the Lydian scale is a major seventh where in the
Overtone scale is a minor seventh.
The tonic is in D, followed by E, F#, G#, A, B, C and D. If you play the
Acoustic scale in E youŽll discover the scales are parallel keys, as are
several other interesting modes.
