OK Here are a few of my own "block-busting" ideas
1. Sequenced Loops.
A couple of my synths have arpeggiators/pattern generators, and there are loads of presets in there which provide food for thought. If frees you from the having to come up with a backing track and can let you jam over the top of it.
Get some good ideas going there, record them and then throw away the instant loops and record your own or even an entirely different backing track to go with it.
2. Go outside your comfort zone
Do you usually write music and then lyrics? Well write some lyrics, simply as a poetic exercise and then use the rhyme and meter to suggest a melody line. What harmony or accompaniment suit that?
Usually do lyrics first? Don't!.. Plug in and jam some musical ideas for a change!
3. Constrain yourself
Give yourself some artificial constraints. Decide ahead of time to write in 7/8 and Eb. And work on that framework.. Particularly if you have never used either. We all tend to gravitate to easy key signatures (I'm a sucker for Dm, and have to consciously try to avoid it these days) and to 4/4 time. My latest price is a 3.4 waltz!
4. Use commercial drum loops or midi files.
This is really liberating. Start with a beat and create a complete drum arrangement before even thinking about the tune. Once you have that, get in there with the bass line. Before you know it there is a whole song just desperate to get out!
And of course at the end of the composition process, you are free to throw away the original rhythm track and create your own.
--------------
All of these methods have worked for me in the past. Usually writers block isn't because you have run out of ideas, it's just that you have been stuck in a rut too long and some new methods of working are what are needed to fuel your creativity!
Good luck!
