Since this forum has been a bit slow on the piano portion (lots of forum-related discussion, and a few owner's reports), I will take one for the team and start a piano-learning discussion. I expect to take a lot of flak, but thickish-skin here…
I am a piano beginner, after a few decades of classical guitar (formal guitar classes for several years as a young kid, although never took exams because that was not my goal…). Guitar has been collecting dust for a few years because the slope of progression in classical guitar repertoire is brutal: it's either boring countless minuettos or virtuoso pieces. For the non-virtuoso, the repertoire is appalling, in my opinion.
Finally decided to took on piano a few months ago, for the love of it and because I needed some cognitive challenge outside of work (neuroscientist here!!! Very familiar with the work of the Nobel prize winners of yesterday, which were, BTW, a surprising choice - very good work they did, but there are literally hundreds of others at that caliber).
I am self-teaching with periodic (but very spaced) online feedback/lesson/comment from my sister-in-law that is a piano teacher but lives in a different city. Because of my guitar background, I have set my learning goals reasonable and in order: my priority is to get hand independence (guitar is terrible for that because there is always absolute syncopation: one hand presses the neck note while the other hand plucks the string…), and slowly get the hang of dynamics, legato, and having even touch across fingers. For that I do scales exercises (50% of practice time), and the only piece that I ever practiced is Bach's Prelude CMaj (WTC 1-1), that I have chosen because I felt it would be a good match for my technical goals.
I am open to suggestions on my next pieces to practice (I intend to practice 2 or even 3 pieces at the same time - one as main focus, and the others for slow advance). I thought of staying on Bach - something tells me it will be a good foundation for the future, and I am in no rush of getting to the romantics… I have a few ideas, and curious to know if any matches your suggestions.
Bring on the criticism…
