Again this year I had students come to me with playing problems that should have addressed in the first week of playing their instruments! In some cases we were working to correct bad playing habits that they had been faithfully practicing for 6 months or more. These were all keen intelligent students, some from band programs some had lessons with a "cheaper teacher".
If you allow me to digress if you are picking your teacher on the basis of price then you are making a big mistake. It's not cheaper in the long run when the student quits because it doesn't work(and at some point that is what will happen) or has to spend twice as much time unlearning all the bad habits they have picked up. Sometimes I hear people say "well they are only starting so a cheap teacher and instrument is all they need" Absolutely wrong! In more enlightened countries only the best teachers are allowed to work with beginners during their crucial formation on their instruments. Again this year all the top flute clarinet and sax players were my students, quality of instruction does make a difference
