One of the aspects of Morrissey's output I've always wondered about is: How much does he contribute to the actual music of a song, typically? We know, for example, what his lyric-writing modus operandi is, with his demo tapes from Marr or Boorer, for example, and his private scribbling time. But how much does he generally contribute to such factors as melody/harmony, chord progression, instrumentation, arrangement, structure, backing vocals, etc. In other words, how 'musically' adept/contributory is he? For lack of any definite information in this area (or at least, my lack), I offer this question: How much do you think Morrissey contributes to the musical element of his songs, on average?
