i am sure i am the worst player on earth, "player", if i can call myself so.
well, i just had few music theory lessons when i was 13, 2 hours per week, that's nothing... that let me know basic things but I never learnt to play any instrument. I spent a lot of time beside my uncle (drummer) and my grand father (violinist) in their studio, then I bought a little Roland amateur keyboard and started reproducing songs by ear... until last year, only at 23, I started learning piano. I must say I'm an average fast learner, but I have some difficulties syncing my two hands
I am not doing classical, I play few things, like "Strangers in the night", "What a wondeful world", "Play fiddle play", "Foule sentimentale", "Solenzara"...
My objective is not to be a great pianist, but to have more practice with chords & harmonics so that my tracks don't sound out of tune & amateur like. I am not trying to make them sound pro neither, just audible
So, somtimes I play live & record into sequencer (especially for strings since i don't have to play fast), but generally I play what I have in mind, figure out the notes, put them on the sequencer & play back
