anger.
if you made this instrument sound. well done. You have demonstrated clearly your ability to create the emotion that is anger, very well. however it is not used in the best context. take your anger out. but instead of just noise....Try enforcing emotions in a musical way that teaches us something, or that we can relate to. at least use this in a song or riff.
The idea is their. and you put it across well. However i did not much care for jumping out of my seat LOL.
take care and learn to channel your anger in less aggresive manners.
goodbye. :D P.S. you deserve some stars to cheer you up!
I care!
