For freshman/sophomore courses in Basic Music Theory, Lower Division Theory and Theory I-IV. With an emphasis on learning and understanding by doing, this text/workbook takes students from music fundamentals through harmony in common practice to some of the more important harmonic procedures of the 20th century. The approach is additive throughout, allowing students to use what was learned in one chapter to help comprehension of the materials in the next. This allows for minimum of memorization since students repeatedly use the concepts throughout the semester.
