Basic Materials in Music Theory: A Programed Course (Fifth Edition)

This programmed-instruction text allows students to progress through core theory topics (intervals, scales, harmony) at their own pace, with built-in feedback and mastery frames. The format is described as “auto-instructional,” letting readers “work independently and at their own pace,” according to publisher summaries.
