I find the initial inspiration for ideas in the shower usually. No idea why, it just kind of happens.

Other things I do is keeping a sound recorder around and voice any spontaneous ideas into the recorder, as well as actually setting time aside with the intention just to experiment with sounds in the studio.

A YouTuber named "Adam Seely" has also suggested that if you limit your options you can access more inspiration and creativity that way. For example: Writing a song only using Minor complex chords.

Setting time aside to do these things usually is enough to get the inspiration flowing.


Cheers,
Joe
