I used to play keyboard at high school. I was an "A" student at it. I could write tunes and play them. I had my own keyboard at home and used to play it often. My signature tune was "The Entertainer" (Charlie Chaplin).......I could play that with both hands....eg, the same as a piano player......left hand doing fancy chord runs and the right playing the melody.......
I then went onto composing dance/trance music using software and the computer.......for my own listening, never played publicly.......
Alas, I havent "tickled the ivories"...or more accurately, the injection moulded keys in years......I miss those days.
