The 10 Best Music Theory Textbooks

For a first book that answers the questions most players actually have, Music Theory for Dummies covers a lot of ground in plain language. Michael Pilhofer and Holly Day start with reading notes and rhythm, then work through scales, intervals, chords and progressions to song forms and a little composing. Each chapter stands alone, so a guitarist can jump straight to chords, and audio examples are online. It reads like a reference, not a graded course, with few drills.

Adults who can't read a note yet get a patient, funny guide in Basic Music Theory by Jonathan Harnum, a multi-instrumentalist with a doctorate in music education. It moves from the staff and rhythm through keys, intervals and chords in small steps, and each chapter ends with practical exercises. Side chapters cover how to practice, conducting and the Italian terms on sheet music. There's no audio, so keep an instrument or a keyboard app nearby.

If reading sheet music is the goal, How to Read Music in 30 Days by composer Matthew Ellul breaks the job into daily lessons on pitch, rhythm, notation and expression marks. More than 100 exercises, listening challenges and a final test keep you working, and the audio and answers are online. It stays with reading and rhythm, so chords and harmony get little space. The extras also depend on the author's website staying up.

Teachers have leaned on Alfred's Essentials of Music Theory for decades, and this complete edition binds all three of its books into one spiral volume that lies flat. Each short unit pairs explanation pages and written exercises with an ear-training page and a review. It moves quickly, from the staff and note values to scales, keys and chord progressions. The answer key and the audio for the listening pages are sold separately, which makes solo study harder.

Visual learners may get the most from Music Theory Note by Note, a DK book with clean diagrams and short sections. This revised edition of a beginner guide by Michael Miller runs from pitch and rhythm through melody and harmony to arranging and writing your own songs, so it suits hobbyists who want to create music, not only read it. Its broad sweep gives harmony less depth than a course text, and this edition is fairly new to readers.

Players headed toward pop, jazz or songwriting can start with Berklee Music Theory Book 1 by Paul Schmeling, a longtime Berklee College of Music teacher. Short lessons on notes, rhythm, scales, intervals and triads each lead into written exercises and ear-training drills, with answers in the back. The online audio can be awkward to find and follow, and this first volume stops at the basics, so harmony waits for the second book.

Small enough for a gig bag, Hal Leonard Pocket Music Theory by Keith Wyatt and Carl Schroeder packs a full theory survey into a tiny paperback. It runs from note names and rhythm through chord building and progressions to modes, borrowed chords and changing keys, with plain explanations and short examples. It works best as a quick lookup between lessons. There's little practice material and no audio, so it won't teach a beginner on its own.

Tonal Harmony by Stefan Kostka, Dorothy Payne and Byron Almén is the course book many U.S. college theory classes assign, and this is the seventh edition. It teaches four-part writing, chord function and modulation up through chromatic harmony, then closes with a look at 20th-century music, using examples from real pieces. It's dense and wordy, built for a class with a separate workbook, and newer editions exist, so check your syllabus first.

Jazz musicians who already read music and know their scales can go deep with The Jazz Theory Book by pianist Mark Levine. It shows how chords and scales fit together, then covers the ii-V-I progression, bebop scales, piano voicings, reharmonization and the forms of standard tunes, with examples drawn from classic recordings. Players of any instrument can use it. It assumes a solid grasp of the basics and comes without audio.

Composers who want tools beyond the rules of tonal harmony still turn to Twentieth-Century Harmony, which Vincent Persichetti published in 1961. He catalogs scales, chords built in thirds, fourths and seconds, added-note chords, polychords and harmonic rhythm, each with short examples he wrote himself. It reads as a compact reference rather than a course. There are no exercises, and you need to know traditional harmony well before it makes sense.
