I`ve been trying to perfect Mozart`s Rondo Alla Turca for the past few months, and I`ve run into some problems. I used to be able to run through it no problem, and I still have all the notes memorized, but when I play it at tempo now for some reason I find myself meshing notes together, especially in measure 34-39, and 41-47. I may also hit the wrong key or miss a note while playing. This piece is burned into my memory, but I still make mistakes...am I not ready to play it at tempo or am I just being careless?

the past few months? Please dont take this the wrong way but it shouldnt take you that long.....i say if it took that long and you cant get it up to tempo then go try easier stuff..
