A few questions on student/teacher etiquette:
I'm an adult beginner (35) starting double bass this year. My teacher selection was somewhat haphazard, and I'm not sure it's a good fit. Before my DB was ready I took several electric bass lessons with the guy, and learned a fair amount re: chord/scale theory and so on. Now that we're on to fundamentals of double bass (5 lessons in), I'm not sure he's providing the proper level of guidance on basics like stance, positions, bow technique, etc. I feel like I really don't want to learn wrong and have to unlearn a ton of bad habits, and I have an instinct that there's no real instructional method being employed.
1) What would be a good sign or set of signs that I should continue or not continue with a particular teacher?
2) If I decide to move on to another teacher, what's the proper etiquette for finding a new one? Apart from his being a really nice guy, I don't want to damage any connections/burn any bridges.
1) The fact that you're asking this is a good sign that you need more info than your current teacher may be able to give you.
It sounds like you should get together with other teachers regarding the issues you're looking to improve. When choosing another
teacher, make sure they have expertise in your desired area of study. If you want to work with the bow, find an orchestra player in a good local symphony, and/or one who teaches at the HS or college level.
2) If you've decided you have had enough with your current teacher, just tell him in a nice way that you've decided
to check out some other approaches and that you appreciate his help up to this point. He may be the first to recognize
his weaknesses in certain areas of playing. Very few of us can do it all. If you still want to keep seeing him, do so, and arrange some lessons with others, too. You don't have to close the door unless you want to.
