By the time of his Fourth String Quartet, inversional symmetry had become as fundamental a premise of Bartók's harmonic language as it is of the twelve-tone music of Schoenberg, Berg, and Webern. Neither he nor they ever realized that this connection establishes a profound affinity between them in spite of the stylistic features that so obviously distinguish his music from theirs...Nowhere does he [Bartók] recognize the communality of his harmonic language with that of the twelve-tone composers that is implied in their shared premise of the harmonic equivalence of inversionally symmetrical pitch-class relations.george perle
Lambert, who admired Duke Ellington and proclaimed his harmonic roots in Frederick Delius (who in his turn had taken them from Debussy), was a fearless reconciler of what the academies and Tin Pan Alley alike presumed to be eternally opposed…In 1972, on a plane from New York to Toronto, I found myself sitting next to Duke Ellington, who spoke almost with tears in his eyes of the stature of Lambert.Constant Lambert
