It's not a weird topic, there are several threads already on this. . .
Ok, I'm probably just exagerrating the title but you get the idea how good the teacher has to be. This thread is just a question coming in from my 'post your teacher's repertoire' thread in Student's Corner. Does a teacher have to be a competent player (i.e. play everything fast, learn pieces very fast) to be a very good quality teacher? I can't remember where, but a few days ago I read a thread mentioning a piano proffessor in a masterclass. I think it was something along the lines of: the professor doesn't play the piano as well as people expect him to, but gave a strong masterclass and the students came out stunned by the instruction they recieved. I know this is weird, but does the teacher (or even, piano professor) have to have an amazing playing ability to be able to teach very good students? Lol, sorry for the weirdest topic yet coming from me. JL
first of all, how can someone teach technique if the teacher himself don't have it?
I think it only makes sense that a "world class teacher" would be a good piano player. But obviously being a great performer does NOT mean you will be a good teacher. Usually really good teachers ARE good players, but good players are not necessarily good teachers. It's interesting, though, because a good teacher can teach a student without necessarily being able to play their piece completely. One of my friends who was auditioning for DMA programs played Franck's Prelude, Chorale and Fugue for me. I have never played it and would have to practice many hours to be able to play it. BUT that doesn't mean I can't critique and comment. I gave him my feedback about different aspects of his performance that helped him play it better.
I think the phrase "those that understand, teach" is true because being a teacher requires so much more than being a performer. Great performers can be masters at teaching themselves and figuring out problems but when the do that often they forget what it is like to be a beginner and have difficult explaining to others. For me because I am an experienced performer I will look at a piece of music and already have an idea of what fingerings to use, techniques and phrasing if I can keep up musically. Sometimes I will have to play the passage to analyze how I would do it just to explain to the student how to play it. My point is performers sometimes do the right thing through muscle memory and when explaining it to students skip the process of analyzing how to get there and get frustrated and use general global words like play louder , or play a stream of wind here etc. All of that is nice flowery language that may influence a student but will not help if the student does not know how to do it. You need technique in order to make musical choices but if the student has the technique teachers can provide the musical knowledge so the student can go toward that goal. If the student is missing this technique however then the teacher should be able to fill in the gap. Ultimatily the definite of good teacher may be not as exact as the right teacher for the student. For a beginner, you want a teacher who knows the instrument well and pedagogy to teach it. For more advance student, a teacher can still be effective even if they are limited in playing ability. However the best teachers in my opinion will work to learn the instrument because they understand the technical side is more critical for most students.
Then I would think the answer would be yes - you need to be a very good pianist for whatever level you are teaching to be a world class teacher. Maybe you teach 1st year only and do not know how to play concertos.
