Or you can say 'the song Bohemian Rhapsody makes use of [insert musical techniques]'. If when talking about film you can discuss elements such as shots/close-ups/slow-motion (that are not literary techniques), and with art elements such as colour, tone, size/shape, medium (statue/painting), I don't see why you shouldn't be able to use musical techniques as long as they apply to your argument. Just don't go overboard; the lyrics are good too.i think if you specify in your essay, "in the song Bohemian Rhapsody (audio)" then your free to analyze how music plays a part in the belonging theme e.g. discordant sounds evoke the tensions of not belonging etc
+1 to this. Exactly what my English teacher told those who were doing music as an elective and thought analysing a song would be an easy way out of extra work.If you are using a song you MUST try to incorporate the musical techniques being used. It is not enough to simply examine the lyrics. You need to discuss things like tempo, tone, key, time signature, key changes, crescendos, major/minor patterns, instrument selection etc. If you can not do this, or don't know what those terms mean, do not do a song.
Not only this, but you have to be able to demonstrate conclusively that certain musical techniques evoke certain emotions or idea. You can't just make an abitrary link between a technique and a concept. Unless you have a background in music, this will be extremely difficult.
Basically, if possible, avoid songs. They are difficult to analyse, and even harder to convey to a marker.
