My First Ever Song (Hopefully One Of Many To Come)

So for our third music class of the semester, we had to have a song all prepared and recorded to show to the class. A scary concept, however breaking it down into small bits made it actually quite simple and for me, quite enjoyable. Split into pairs, my partner and I (Natalie) were given several poetic phrases and were told to create a song using some, all or none of the given phrases. They were:
"I breathe in, the cool air, that the colour of the sky gives me"
"After so much mist, one by one, the stars unveil"
"I know I am a passing image"
"Caught in an immortal circle"
The general idea we got from these quotes was that it was quite a sad message about being trapped and longing for a sense of freedom.
We structured the song like a modern day pop song (Verse/Chorus/Verse/Chorus/Bridge/Chorus) as this would be the easiest and simplest way of writing for amateurs like ourselves. We also settled on the general dynamics of the song with a relatively quiet verse, louder chorus which builds to a strong and loud bridge to link with the end chorus, creating that climax of being free and breaking out of the monotony of being trapped.
Splitting up the writing between us made sense at it gave us both a bit of creative freedom before meeting and filling in the gaps (the bridge we did together).
When writing the two verses, I used the first quote as a starting reference and began to build it around that. After writing two lines of the first verse, putting 4 simple and rather random chords (literally played the first 4 that came into mind) helped me to write the rest of the first verse which in turn helped to shape the second verse through the general message I was trying to convey from the first.
There are songwriters that write songs either of two ways. One group tends to write lyrics, then add the music, while the other does the converse and puts lyrics to music. I found that when writing, I tend to side with the group that puts lyrics to music as I personally feel that it's easier to write lyrics when you know the tune of the song, and it helps to stop lines either being too long or too short (you could argue that it restricts your creativity because of the fact that you have a 'musical deadline' (lack of a better term), but again, just my opinion.
Enough of my rambling, and on with the actual finished work (apologies for the variation of volume of my singing, that's what tends to happen when you're ill)
Enjoy!
