For me, fooling around on the keyboard does wonders. I'm still new at it (been playing for 16 months now) but love it to pieces. So I just mess around with my fingers, seeing what good combinations I can get, e.g instead of right hand C, left hand C, how about right hand Cmajor, left hand G (the note)---and what can follow that, say right hand Fsus4, left hand F the key, then right hand F major, left hand G the key. I then get onto another keybaord, play it out and add the rest of the instruments, i.e drums, strings, percussions etc.
Once the trak is done, I then wait for inspiration to give me a song. So I could be in a congreation of 3000, listening to a sermon, when a word of knowledge goes out to this one person and I think to myself ---"who can pick me out from a crowd ? "--- and that's one line to a song. Nex' day, i'm on the line in the supermarket, waiting to pay for groceries and just when I get to the till, i'm the hundredth customer so I get a 40% discount. Then I think to myself, "Who can show me favour without ulterior motive?"
A few days, or even weeks later, I realise that all along, God has been mercifully holding me and that's why I never back backslid. So I think to myself, "And who'z the one anchor we all need to know hold?"
Put these three lines together and you may have a part of a song.
Thing to remember is this; a song could take 10 minutes to create; it could also take 10 months 1---additions, deletions, changes to tempo and tones etc. There's no specific formula coz when song creation has a formula to it, then the soul in the song dies and that's when it all becomes mechanical. Kinda like Rice and bread for dinner---aint nothing wrong with Rice or Bread except that that particular combination lacks "soul".
