As you can see from the last post, what I have been saying about different forms holds true: it’s possible to use lines of poetry in song and lines of song for poetry; both examples show that. Why did I cut off down a different path for each then? Well in this case, the poem is concise and doesn’t need embellishment of either further words or of musical backing, while the song has a musicality in its lines that suggests how it might go – it doesn’t sound like something you’d just read out.
As imprecise as this all is, you only need to know what to do to write something that works. If you are going to present something ‘undernourished’, I suggest turning up with some ideas for how the song might go. Otherwise your sketch might be overlooked for something more ‘song-like’
