Improvisation Is The Future

OK well I'm back in school tomorrow, which is neither good or bad. Now my plan was to record a song during my music lesson for my GCSE the way I shall do that is by making up a riff/chord pattern now and tomorrow I'll make up the lyrics as I go along. This could be fun, especially since I'll put that forward to my teacher using it to get my music GCSE, I can't wait.

A Little Dilemma

I've ran into a small problem where I have an intro riff and i can't think of anything to follow it. This makes me sad and I don't like it. I have the start of a song, and nothing else, no lyrics, no verse riffs, nothing. However the intro sounds a little magical so I expect the lyrics to be about unicorns and elves.
As a side note I may consider putting the old keyboard that is in the spare room to use. Nothing wrong with being a multi-instrumentalist. (If that isn't a word it is now).
