Intermediate Students have usually been playing violin anywhere from three to eight years and/or are working on RCM Grade 4-9. I find that the biggest challenge most Intermediate Students face is that their bodies and minds start rapidly changing by the time they get into their teens. Availability of violins in different sizes can somewhat rectify this problem, but nonetheless students often have to rediscover their balance and change the way they have been playing.
Furthermore, the repertoire these students play gets much harder and it is often necessary to correct some bad habits that have been developed earlier, but haven't really bothered the student, since he had been able to play and do everything that was demanded of him. This warrants a more serious approach and a significant increase in practice time. Also, the Intermediate Student has to start exerting more control over his playing. Heinrich Neuhaus, one of the foremost piano pedagogues of all times writes about a student who "because of technical difficulties or some other reason plays what comes out and not what he wants or thinks, or - most important of all - what the composer wants". Hence, Intermediate Students have to start bringing their technique to a level where they are able to accurately express all the composer's intentions.
