The intervallic content of the E Flat Lydian minor 2 Scale. One of the interesting harmonic artifacts of this altered scale is in the sequence of fourths - tritone, tritone, perfect fourth, perfect fourth, perfect fourth, diminished fourth, perfect fourth, tritone - that points toward some interesting properties to bring out in performance. The presence of the extra "tritone" along with the harmonic ambiguity of the equal tempered diminished fourth (which can cognitively pass for a major third) sets up some unusual situations. Also, the minor second and augmented fourth degrees help eliminate the all-too-common ii-V-I progression by completely altering the subdominant/dominant properties of those harmonies.
