Adults who studied earlier in life and would like to start again Singers who would like to learn to accompany themselves Songwriters and music producers who want to play better in order to express their musical ideas more thoroughly Piano teachers who would like to develop their improvisational skills Voice teachers who would like to better accompany their students Musicians who play another instrument, but would like to master the piano. Lessons are tailored to the student's level and area of interest. If we liken learning music to learning a foreign language, we might say that Ear Training is like trying to hear the language and understand the words. Sight Reading is like knowing how to fluidly read the written words of the language. Improvisation would be the ability to expound freely in that language whether in conversation or monologue.
Music is a language, with many different dialects.
We study many of those, and find that they're usually related to each other in some way. Listening is closely related to ear training, and involves listening to recordings to understand and identify what is being heard. Theory is the study of the underlying structures in music and should always be useful and applicable to playing. Technique is the ability to physically be in command of the piano and not have it be in command of you. Repertoire is the body of songs and pieces that the pianist learns.
