Crap, man! That would be a tough gig, I think.
...where to start?
I guess if it were me, One way to begin, would be to get a consensus on what type of music the class already likes, and look into that (or those) specific genres to see how best they can emulate...maybe.
The other side of that - probably the route I'd take - is not only to get a handle on what floats their boat currently, but also to expose your students to other great songs that they may not have heard before.
Haydn was a melodist and believed that a truly good tune could survive without any accompanament (i.e. what sounds good when sung in the shower.) Do people like the guitar part to a recording more than the song itself ("Stairway")? Does everyone know all of the words to "American Pie"?...I bet most will. Lyrics vs. Music...what a battle!
IF it's the world of standards, you could look at the greats like Hoagy Carmichael, Cole Porter, Gershwin, even Woody Guthrie.
Other candidates worthy of study, IMHO would include Elvis Costello, Mary-Chapin Carpenter, Lenon/McCartney, Lucinda Williams, John Prine, Jimmy Webb, on and on...AND I've always told people to listen to "Nebraska" by Bruce Springsteen to hear just how powerful a song can be with just scratch vocals and basically shit-for-production guitar tracks. It's ONE strong example of the raw power of a song.
There are many more that I'm sure folks will post here - as well as bring to light in your class.
I generally write country songs from the hook down. Pop/rock tunes can come from anywhere...of course they ALL can but that's been the scenario for me lately.
You can use John Denver's"Annie's Song" to illustrate that a good song need not rhyme at all.
Topics for songs can come from anywhere - as we all know. I tend to write from experiences - both personally, and also other places...just overhearing people at the gocery store or the bank. People DO say the darndest things! Put it in a song. Some of the things on that Bruce album generated from memories from his childhood. Something nagging at you for 10 years?....deal with it in a song. Zeppelin generated a lot of stuff from the world of Tolkien (and other 'mystic' sources), Peter Gabriel from political figures (Biko) and literary folks (Anne Sexton spawned "Mercy Street"). Again, there are countless others, but the ideas are everywhere.
I assume you will have class singing/critique sessions?... to really help extract and refine things.
You have a possibly big task ahead...albeit a fun and rewarding one, I think. I hope this helps you generate more ideas for your course.
Let us know how it progresses.
Good luck!
