ABSTRACT: the development of a string quartet is a complex, long lasting task. the pedagogue plays a significant role in this process, which can in turn be very demanding, given four different personalities and levels of musical comprehension and ability have to be shaped into a unified whole. the present article deals on this issue, and the differences between a solo instrumentalist pedagogue and a string quartet-oriented pedagogue, encompassing different facets that are entwined in the whole development process: on the most effective practice, issues of automatisation, the development of listening skills, intonation practice, and goal placement. last but not least, the article dwells on successful rehearsal preparation, outlining the core distinction between the approach and preparation that would be required for the solo repertoire and that for a multi-voiced quartet composition.
