hi steelstrings,
i agree with everything written above.
my own method goes like this;
1) i may be practicing and a chord progression comes to my fingers followed by some words, they may not be sensible words but that matters very little at this point, as words can be re-written later.
i try not to think of a subject before hand, as that gets in the way quite often.
2) at work, i sometimes have a minute and a line or a fraze my come to mind, so i write it down (it's always handy to have pen and paper handy!). if you have a mobile phone with a recording fascility you can capture any tune on that for later reference.
3) keep a note pad and pen beside the bed. i get a lot of songs popping into my head as i wake in the mornings.
4) i allow the song to dictate the flow and/or story line. a song may seem to be heading in one direction in the first line, but by the 2nd verse it may be taking you somewhere far more exciting.
finally, dont concentrate on love songs or driving songs. or heart-ache or beer! a song can be about any subject you choose, so dont worry too much if it comes out as a story about your
sunday lunch.
most of all enjoy the experience
