All teachers teach Bach. Pick any Bach piece you want, regardless of difficulty, and they will teach you. The only thing you have to do is hold up your end, i.e. learn the notes, rhythm and have it under control.
My teacher told me that Chopin regarded Bach as THE greatest composer, and Chopin played all of Bach WTC 1 & 2 among other Bach works.
I remember learning Bach Prelude and Fugue in G major from WTC 2, my teacher adds in staccato and some other articulation markings to add shade to the music.
All the piano teachers I learned from who play the toughest virtuoso romantic pieces by Liszt, Chopin, Brahms, Rachmaninoff etc. all play Bach. One of my piano teachers just loves playing Bach and she knocks all the Chopin Etudes, Liszt Etudes (Transcendental, Concert, Paganini) among other hard pieces, out of the park.
Pros
- WTC develop skills in voicing
- play right notes and right rhythm and it's yours
- Who cares about musical expression in Bach
- No real style
- Very rewarding if you can play Bach
- ALL piano teachers WILL teach you ANY Bach piece you want
Cons - Why I hate Bach so much
- Mindblowingly hard to memorize
- Technically difficult pieces (even the easiest Bach you can name)
- Extremely boring music
- No interpretation demands
- Super hard to learn
- Teachers make Bach harder than what it should be
That was what I thought of Bach before.
How can playing Bach help me become a better pianist?
