Finding The Right Music Teacher
If you have done the prerequisite research I mentioned then this should not be an issue. However, guitar playing is such a personal undertaking that finding the right teacher is relative to each student. What works for one, clearly does not always work for another.
Your teacher should care about you and take an interest in seeing you advance as a player. If this were not the case, I think this would be the biggest red flag to me if I was taking lessons all over again. I would want to know that there was some nurturing involved. If you feel that there really is no connection between the two of you then I think this might be a factor you can use to determine whether you move on or not.
It’s tricky. As a student you want the best teacher for you, but you may not know, if there is no barometer to show you.
I also think that many times the student is to blame for being a lousy student. I remember when I used to give private lessons. A few students would come back week after week and had done no practice at all. I found myself explaining the same things over and over and of course we couldn’t move on until the essential groundwork was covered. These students eventually gave up because they had no drive or ambition to improve. This can be very frustrating to the teacher. Other times extremely talented players would come for just a few lessons because all they needed was a little fuel to go off on their own and practice. They were literally sponges. These students are heaven for teachers!
So do the research, then take a lesson or two and see if that teacher is right for you. If you are serious about working at your instrument then you shouldn’t be to blame for being a bad student. At that time it’s simply a matter of finding the right person. Don’t short change yourself.
