Steps to Music Theory is a music theory textbook that explains concepts step by step. Chapters are divided into 8-12 sections so that students can instantly jump to any specific section. Nearly every section ends with one (to as many as six) Practice Sections, where students can go through problems to see if they understand the concepts.
There are several advantages to an online platform for a music theory textbook. First, students can listen to musical examples while they read. Steps to Music Theory contains hundreds of musical examples, including many by women composers. Second, every Practice Section includes a video lecture, where the author goes through the steps to finding the answer.
