Hi Bernie,
maybe a bit of an odd question, are you planning on playing solo piano, or piano as part of your arranger playing ?

What I used to enjoy playing all those years ago, was of no use to me when I eventually became interested in keyboards.
The solo piano sheets, quite often didn’t even have chord symbols, and the style I liked , left hand arpeggios didn’t lend themselves to keyboard at all, so I had to start over and learn what chords were. Haha.

With the online lessons I’m currently taking, I’m hoping to finally work out how to incorporate l/r hand piano into arranger playing, without just holding a left hand chord down. The course is sort of helping me think for myself instead of doggedly reading every single note, which probably wouldn’t work for left hand anyway, I’m not aware of any arrangements written for piano/arranger.

The solo piano sheets I’ll just treat seperately, and try and relearn ( if I can be bothered)

Main thing is , having fun.
