Two reasons why writing to inform is creative writing is because it doesnt always have to be real and your using your own thought process.
I'm not entirely sure but I think it would be order of importance.
Just pick your favourite song, google the lyrics for it, fill in the writer's name in the line after "writer:", then do the same for the performer but with the performers name. explain why it's your favourite song and what it makes you feel.
then below, pick out a line in the song and put it down, and on the other side, explain what it makes you feel. example : "I'm nothing special, in fact, I'm a bit of a bore." (by abba) ——— it makes me feel understood? like I can relate? (or something like that, you know.) then do so for the rest of the boxes.
then, put in a rhyming line and explain why you like it. next, describe the beat of the song. is it fast? slow? smooth? is it something you can dance to? does it sound energetic? does it sound calming? then explain why it makes you feel that way.
lastly, describe the singer's voice in the song. are they singing clearly? or in a low voice? a high voice? then explain how it makes you feel. does it make you feel calm? does it send shivers? does it make you remind you of someone else?
i hope this helped! xx
An art song is usually for solo voice and is accompanied by solo piano. (Just as a side note, I recommend listening to the Erlking by Schubert if you have time; it's a German art song (lied))
