When looking for a teacher do not focus just on the financial aspect. Many people decide if they will take lessons with a teacher or an organization based solely on the price.
There are many other things to consider. Here are a few that one can keep in mind while shopping: location, individual lessons or group lessons, how long are the lessons, what is the experience of the teacher(s), what style is taught, is there a progression during the lessons, does the teacher take into account one’s musical background, will the teacher understand the time One will spent practicing.
I have been successful, I think, because I never neglect the different aspects of my job. Mainly, I tailor the lessons based on what the student tell me he/she wants to study. It gives the student the course they are looking for and my lessons are never the same.
