Instrumouthing 

The act of mouthing key instrumental solos in songs, weather it be guitar, bass or even percussion.

When you are listening to a song and you join in by mimicking the instuments with your mouth you are now instrumouthing. A good example of song to do this to would be Sweet Child of Mine by Guns N Roses.

Instrumorphing 

When you morph instruments or vacuole into different instruments or vocals in the production of a song

I really liked the instrumorphing in AJR’s new song.
