Do you use a particular piano method or curriculum, like Suzuki or Bastien?
I’ll occasionally find a piano pedagogy book which works well in a particular circumstance, but I generally tailor each student’s repertoire to his/her own needs and personality. There is such a wealth of piano repertoire to choose from that there is no reason for all of my students to play the same pieces! My primary focus is on classical music, including music by contemporary composers. Some students also enjoy working on high-quality arrangements of traditional songs, ragtime and jazz, which can compliment this classical repertoire. While I often give students choices between two or three pieces of music, I generally don’t teach popular music which students bring into their lessons. I see my job as giving students the skills they need to learn a wide variety of music, both in the studio and at home.
