she's even talked about Waddy finding her stuff a bit boring and unchallenging in terms of having to play the same chords over and over and over.
Wasn't it Ken who said she only knows 3 chords but she can write you 40 songs with those chords?
For a while, like during the 70s, she kinda tried a lot harder with her piano playing because she felt a bit self conscious about how poorly she played compared to Chris. (Listen to her playing on the demo for Sisters).
It felt like around the solo album era she really just kinda slacked off (Listen to her playing on the demo for Bella Donna--- and don't confuse the one of her playing two fingered piano with the demo of Roy Bittan playing
)
She did for a time say she considered lessons but people around her told her if she started learning and worrying about following rules it might stymie her creativity.. she says "even Lindsey" told her not to mess with it.
Maybe he was just being evil and didn't want her to be better formally trained than him.
