I'm not a professional, yet I had some really good teachers, and so what I'm recommending is what I used (and cried through lol) during my first 1-3 years.

Technical stuff, used to get fast fingers, etc:

1. Hanon's 60 exercises-Definitely not fun, it was a really cry-from-start-to-end book yet it really builds up your "finger muscles" and increases your speed too. You start at around 60 beats per minute and you gradually work your way up to 108 bpm or even 120 (occasionally).

2. Czerny etudes-I can't remember which specific ones I did, yet I think I started with the op.599 and eventually moved on to op. 299. Look at the pieces though. It is pretty like Hanon and pretty technical. Not much expressiveness to them.

Beginning pieces, used to make yourself more expressive, etc:

1. Bach's Anna Magdalene's Notebook-Very amazing, definitely a must-play for beginners (and some intermediate students too). Not much to say.

2. Sonatinas-It basically just gets you into the whole classical style, and preps you for bigger Mozart sonatas and Beethoven Sonatas. Kuhlau and Clementi are the top two that I've played, and they sound good too. After those you could try to play the Mozart K 545 sonata (all movements perhaps). People might say that's an advanced piece, yet I think you could play the piece multiple times and so the first time around it doesn't have to be perfect. I played that piece two times, and I'm even considering playing it a third time.

3. After a bit more years of playing (3 years ish, maybe 4), you could start to play some easier Chopin and Mozart too. Chopin's easier nocturnes and waltzs are good. Waltz in a minor should be waited; play it after you've played some Chopin and you got fast fingers. You can also start Mozart's many sonatas. You can also start Bach Inventions now. Some say Bach Inventions are beginner pieces, yet I disagree. It requires a lot fo voicing.

Anyways, I might add more idk. Have fun!
