I've had an idea...
What if one of us were to post a basic set of lyrics with a simple chord structure. A song of maybe 2 or 3 verses with a chorus, nothing too complicated. The lyrics to be set out with the chords printed above the words in the relevant places to help define the 'tune'. (Lets call this the blueprint).
Each of us (whoever wants to) has a play with the blueprint and comes up with his/her own melody, harmonies, rhythm, tempo, genre etc to create their own interpretation.
Record your interpretation of the blueprint and post a link to the thread.
We can then listen to each others interpretations of the same basic song and see how different they are. With the diverse genres/styles of music I've heard on this site I reckon we could end up with a whole bunch of tracks, each sounding completely different to the next.
What do you think?
