<p>Like everything it depends on the situation at hand, there are no firm rules from where I stand. Master teacher itself in some ways is ambiguous, because what does that mean? Someone who has proven themselves great at teaching (and if so, by what measure do you use? Admittance to conservatories? Where the students ended up eventually?)…Someone who has achieved great professional success (lots of high level musicians teach, some are great teachers, many are okay, some outright stink as teachers). Someone who has taught a lot of years? Not necessarily a sign of a master teacher, just someone who has taught a long time. And even a master teacher might not have the information needed for a specific goal, such as how to get through an audition at the college or conservatory level, so there a younger person who knows what the deal is for auditions, for example, might be better then some meister teacher. </p>
<p>That younger teacher, on the other hand, might be great at the things that help a kid pass an audition but misses other things that make the difference between being a good and great player. In the violin world, there are teachers, for example, who are notorious for focusing on goals, like getting kids into a high level prep program or winning competitions, and do so pretty well, but then the kids are lacking some really important things that have nothing to do with the auditions or the competitions that later on can hurt them, even if they end up in high level programs. </p>
<p>One point I will make is that sometimes it takes more then one teacher to achieve the goals you need, there are plenty of teachers (as mentioned even in the link that re-vitalized this thread) who have another teacher work on technique and technical points while they focus on the musicality and interpretation of pieces and such. A master techician, for example (the “romantic” as used in the link) may be great at that in teaching, but not good at the artistry, whereas another teacher is great at artistry but not as strong on the technical, so both might be useful:).</p>
<p>One thing I got out of this article is that given the polarity it talks about, that a good teacher for a particular student might be someone who balances the student out, that the more ‘naive’ musician needs a ‘sentimental’ majority teacher (forgive the wording, I mean someone who is shifted in balance more to the technical) while a student who is technically strong (sentimantal) may want a teacher who is more ‘naive’ (artistic, musical, whatever). Which means no ‘master teacher’ could work for all students, which I suspect many people on here figured out along the way:)</p>
