Past research has referred to either the concepts of self-regulation or deliberate practice to explain the relationships between learning strategies and musical achievement and performance. In addition, even though most scholars agree that formal practice time plays an important role in musical achievement, empirical investigations have failed to show consistent associations between practice time and achievement. The aim of this article is to suggest an integrative framework in which self-regulation, deliberate practice strategies and practice time are simultaneously taken into account in the prediction of musical achievement. In this framework, we propose that formal practice should be defined as a goal-directed and focused period of practice that includes both self-regulation and deliberate practice strategies. We further posit that practice time will predict musical achievement only if associated with formal practice. This integrative framework was tested in a 4-month prospective study using structural equation modelling. Results revealed that this integrative model was a better predictor of musical achievement than traditional methods of measurement. The suggested integration of self-regulation and deliberate practice within a single framework provides a more complete picture of the associations between learning strategies, practice time and musical achievement.
