I never thought about myself as introvert, but often as a hermit. We painters are a lonely breed. Not sure why it made me moody, they come by often, my 19 year old niece sleeps over every Tuesday and the boys agreed to come visit us in the weekends when the summer holiday is over (the youngest one wanted to come every weekend!) They are more like brothers and sisters to my daughters really and my childhood was much the same, only we had uncles, now I am the uncle :)

Check out Toru Takemitsu also. And is you like flute try to find some shakuhachi flute. It is very beautiful.
