Our work highlights the necessity of revising the materials employed in instrumental education, which are systematically based on a progressive development of technical abilities and, though only transversely, without a structured sequence of contents, on issues referring to the interpretation of different periods and styles. In order to elaborate teaching resources systematising the stylistic contents in instrumental education, we propose and justify the use of a research methodology from the social sciences: Grounded Theory. In conjunction, we present a guided demonstration on how to put into practice this methodological system to analyse musical performance based on the concept of Historical Performance of Music and we create related pedagogical resources.
