Welcome to Pianostreet! I know exactly how you feel, since I also started as a mature adult and found it difficult to find suitable easy music.Check out:Kabalevsky op 27, op 39 and op 89Shostakovich op 69Prokofiev op 65 Casella op 35Dello Joio Suite for the youngBartok (there's too much to list)Stravinsky Les cinq doigtsSatie has some rather simple (although not necessary easy) piecesAlexander Tansman (lots of beginner music)And get this book, I promise you won't be disappointed:https://www.amazon.com/Pianists-Standard-Teaching-Performance-Literature/dp/0882846558
BTW. I would forget about the inventions and Bach in general for now. They can be extremely frustrating even if simple looking and most won't start on them until a few years study experience. So much is about finding good fingering and you need to know your hands and be experienced to do it well.
Probably well within the realm of reason to take, say, everybody's favorites like the C maj or D min inventions.
But for an ear player like the OP, with an interest in improvisation, that doesn't seem so bad. Probably well within the realm of reason to take, say, everybody's favorites like the C maj or D min inventions.
Actually, I tried to play Bach Invention 13 a year after starting to play the piano. While playing the notes was hard but manageable, committing that thing to memory was absolute torture. I left it after finishing half a page.
Nice to be able to take baby steps without playing things called "Dance of the Baby Elephants" and "Teddy Bears' Teatime"
Well, sure. If there's anything more difficult to memorize than Bach, except for maybe Schoenberg, I'm not aware of it.
How 'bout Sorabji?
If the OP is anything like what I was, I would expect the fingering in the right hand to be a breeze, but to get slightly confused with the fingering in the left hand (in most contemporary contexts, the left hand plays the role of the accompaniment), and absolutely bamboozled when trying to coordinate both hands.
Also from other experiences that I also had as well when I just started playing piano was that my posture of my hands were always flat and sloppy so that I would always hit something on a wrong key. My suggestion would probably be to just be careful of your hand posture at all times and just make sure that none of your fingers would stick out, because that always leads to clumsiness for me haha.Also feel free to check out this technique on improving hand posture as well!What I would always do is that I would have like a small coin such as a dime or nickel and just place it on top of my hands as I would be playing piano, and the goal is to be able to play scales or songs without the coin falling off. Continue this for about a week or so, and I guarantee that your hands will be in a much better posture than before!
