Hi MsGyver! Yes, I taught myself how to play the piano, and then advanced to the keyboard/digital piano and organ. They all require the same musical theory to read notated sheet music. My mother, however, was already a pianist and gave me a foot up with reading notation. I later discovered my gift for sight-reading sheet music and song writing. I've reached the point where I want to work at music professionally when I've immigrated to Thousand Palms, CA from South Africa. I should be out of South Africa in under 2 weeks, after getting my passport.
You sound like you have much talent with regards to piano playing, sheet music theory and song writing. Good luck with taking your musical talent to the next level! As one recently diagnosed with Aspergers, I have always been fascinated with those who are great at playing a musical instrument, and those who love to write their own songs, too. It's because since youth, I always had dreamed of playing original relaxing and inspirational type songs on the piano, to complement my very good singing abilities.
I just think it's a whole lot easier for me with regards to stage presence, if my focus is on singing and learning to play piano at the same time, while being seated, than standing. Then I can concentrate on my playing and singing and showing natural personality and feeling there, without worrying about cameras and movements too much, instead of trying to be someone else as a singer standing, where I would have to show some hand, arm, leg and body movements on stage that do not seem natural to me, and which seem more rehearsed and fake.
These days it seems like a great singing voice won't go far, unless something else is there also. This means I feel I might need either some entertaining, extraverted, unique and/or believable stage personality, besides my voice, to take me as a singer to the next level. Singers must have some great luck, but also must be seen as fascinating entertainers, to make it far it would seem. That's why now my focus is on piano, and learning to read sheet music well, and with a desire one day to have songs written by me and/or with collaboration from one with Autism or Aspergers, than could understand.
Thanks for posting. Hope to see you around!
