I've been playing/learning keyboards for a while now and the book I'm using is TERRIBLE.I haven't learnt a great deal from it and what I did learn is probably stuff I could have worked out anyway.
What I didn't like is that:
- It was focused too much on left-hand chords and not actual keyboard basslines.
- It didn't actually teach me to read the treble clef (although I worked it out anyway)
- Most of the songs were so adapted/watered down they sounded horrible.
- There was no real teaching of music theory for keys
- There was a brief explanation of scales/arpeggios but it skimmed over a lot of it
So, can anyone suggest any REALLY good keyboard lessons book/course?
