The main approach of popular music is "melody over chords", which also dominates the Queen songbook compared to the melody against melody (counterpoint), melody against riff (somewhere between the former two). The choice of chords in context of the homekey is an interesting point of analysis and a key feature of the analyses. This approach enables one to compare harmony-wise songs in different key easily.
In this book there is hardly any standard notation used. This may be a plus for the ones (many guitarists) who can't read standard notation. We use alphabetic notation instead, that's the way how Mercury would notate his own vocal harmony arrangement sketches.
