The epic grandeur of Der Rosenkavalier stems not just from its immense length (over three hours) but from the all-too-human complexity of its characters–each of whom is smitten with someone else–and the endless stream of graceful melodies the composer conjures. After the tonality-stretching dissonance of Salome and especially Elektra, Strauss moved onto a different musical path here: the music's sheer gorgeousness has given this most heartbreaking of 20th-century operas its pride of place in the repertory.
No musicians are credited except for the associate producer title given to keyboard player Larry Knechtel and retaining Bread photographer, Frank Bez, as well as engineer Bruce Morgan, who played an important part in David Gates’ First from 1973 (and who would engineer Bread’s 1977 comeback, Lost Without Your Love ).
Richard Strauss was filled with doubt as to whether he would be capable of expressing in music the crazed revenge of "Elektra" after writing his opera "Salome" with its shocking story. It is quite understandable that he had trouble in composing the work, although such difficulties are not in the least evident during the course of the drama or in the musical flow. Drawing on natural sources, the forceful melodies make use of polyphonic, complex motifs and extreme dissonances. Here and there, Strauss’s typical chordal harmonies gleam through, though hardly audible, taking the harsh dissonances and chromaticism to the very extremes of atonality.
