It's like a beat, its like a mode...
You know some days you find your mode, and your in it, and you just go and get things done. You know? It seems when I find my mode, I beatbox. On days when I have found my mode I beatbox for like 5 minutes in the shower, just exploring sounds and reflecting the day off tile walls. On days when I'm not in my mode I'll just walk and think where's my mode while hitting different sounds. I throw in some clean bass or distorted bass, hi-hat, snare, techo stuff, industrial stuff, whatever. I just start hitting beatbox buttons until I find something that feels right, bust it for a minute or two, and boom I'm in my mode. Its great, you should try it.
