I've been talking to a lot of music teachers all over the world. A common complaint is that there's "too many distractions" in students lives nowadays. They blame the Internet, or the video games, or soccer or Instagram or other social media.
In my 8 years of running my kid-focused music studio, I have rarely experienced anyone quitting due to distractions or other things. Maybe it's because I interview the parents and make them know what the expectations are. Maybe because I charge more than a lot of other teachers.
What I think it really is, is having a plan. Having a clear plan of what to teach each and every child every lesson.
Because I focus on such young children starting at 3 1/2 or 4, I really had to invent a lot of my own methods. Over the years this method has grown and my teaching lab of daily lessons has honed it to a codified, powerful, and engaging system of teaching.
