These are your songs
The two song selections linked below are examples written by the co-editors of Music Cultures: Journeys into Sound to 'indicate' style and approach. They are intended, in other words, as guides to writing up your own song choice. Although each example is similar in linking the personal to the cultural / historical, they are also very different pieces of writing. So there is no straight-jacket you should wear when writing your mini-essay. Be fearless. Do your song justice.
