Interpretation and Expression: A Workbook for Musicians is based on an approach to music expression that relates changes in sounds that occur in our environment to changes in sound that occur in music. Recognizing how sounds change and how we respond to those changes forms the foundation for developing an understanding of expression in music. The workbook is divided into two parts. Part I includes an expressive methodology and sixteen sound-change exercises and Part II includes a collection of music that is divided into two groups: “Music With Words” and “Music Without Words.”
