Loads of things could've been inspired by loads of things. Even if you found a classical (or popular) piece with 2-3 bars in common with Bo Rhap
, it doesn't necessarily mean it inspired it, let alone that FM borrowed those measures. More than taking parts from classical pieces, Fred employed certain 'tricks' common for the genre, for instance:
* Bitonality ('Galileo' bit), used by a number of composers, including Mozart, whom Fred was quite influenced by.
* Mozart also used a section with four 'no' in a similar setting. The arrangement's very different though.
* The way certain motifs are recycled, transposed and varied.
* The triumphal I>V ending ('for me').
* The way the bass-voice counterpoints the other ones.
John hated HS. Frederick's favourite singer was not PR. Roger didn't compose 'Innuendo.' Witness testimonies are often inaccurate. Scotland's not in England. 'Bo Rhap' hasn't got 180 voices.
