I'm currently working on a little music project, all the stuff so far is instrumental guitar (I hope on having songs with lyrics when my writing gets better). I have no way of adding percussion or other sounds at the moment, so its just me and my guitar until I get my keyboard working. I just wondered what you guys think about having no percussion in a song.

Tl;dr No percussion, yay or nay?
It didn't take long to realise
The safest place was not her arms, but her eyes
Where she can't see you
For her gaze, it blisters;
Grey skin to cinders

If you're trying to write a hard rock song or something then it'll definitely suffer without drums, as they add a lot of 'drive' to music. Same thing if you're trying to write something with a groove to it, it'll need drums to really get it working.

Other than that though, it depends on the music.
