This paper studies conceptions of woodwind students regarding learning and teaching music, within the framework of implicit theories. It analyzes whether there are differences related to participants' instruction level, and whether it is possible to identify profiles according to their conceptions. Sixty-eight students from three different levels at 14 Spanish conservatories took part voluntarily in this study. A multiple-choice questionnaire was used, which comprised 16 dilemmas on different situations typical of learning and teaching music. Three answers were presented for each dilemma, corresponding to the three implicit theories identified in recent years: direct, interpretative, and constructive. For each dilemma, participants were requested to choose the option they most agreed with and the one they least agreed with. Data were analyzed using chi-square tests of independence, multiple correspondence analysis, and ascending hierarchical classification. From the results obtained we can state that as students' age and level of instruction increase, so does the level of sophistication of their conceptions. Three conceptual profiles were identified: direct, direct-interpretative, and constructive, which are consistent with prior results on conceptions of teaching and learning in other domains. Implications for education are discussed.
