An Augmented Scale Sequence
The Augmented Scale wasn't much in evidence in its use by improvisers before the 1960s. It's unique structure, tonal limitations and resulting dissonant character, had made it less than a "go to" for many improvisers in the traditional sense.
As melodic and harmonic concepts opened up in '60s music, the Augmented Scale began to receive some well deserved loved, but to this day still seems to be somewhat misunderstood and underappreciated.
