I'll give it a go when I have a spare half hour, but I will say here that it is a wonderful feeling when simply jamming on my guitar a nice sounding riff comes together, like "I'm responsible for this sound."

Or when finger picking and the next thing I know I'm forming lyrics in my mind to an improvised acoustic piece, I think my mood definitely influences the direction my playing goes in. Like when I feel... Melancholic perhaps, I'll just pluck away on my 12 string, or when I want to blow off steam I'll fire up the Fender amp and rock out for an hour. Both have me feeling happy when I'm finished, good music either played by me or listened to always has that effect.
