Hey there,Finally i got the chance to play piano. Im kind of sad that i started playing at the age of 18. Admittedtly, i always dreamed of playing the piano. But due to the limited budget of my family ;/ I started kinda late. So thats why I dont want to waste time and practice as much as possible!!I dont know which piece i should play next. four months have passed since i started playing . So its obvious that i have only learned three pieces which are , an easy bach prelude BWV 935the 4th bach invention and the first movement of the moonlight sonata. my next piece should help me my improve my technique and sound good ^^ if possible. I would be happy for any suggestions and advices. Are there pieces that every pianist has to struggle with in order to improve ?thanks in advance
