Best music theory books

Before buying anything, be honest about which of these you are: someone who wants to understand the music they play, or someone working toward an exam or a degree. The books that serve those two aims well are almost entirely different.

If you are teaching yourself from scratch

Alfred’s Essentials of Music Theory

A three-book graded series with exercises and ear-training material. Unglamorous, thorough, and paced for genuine beginners. It is the closest thing to a structured course you can work through unsupervised, and it does not assume you can already read.

Music Theory for Dummies

Better than the branding suggests. Plain language, sensible order, and it covers a wider range than most beginner texts, including rhythm and form. Light on exercises, so pair it with something that makes you do the work.

Open Music Theory (free, online)

An open-access textbook maintained by academics, and genuinely good. Because it is free there is no reason not to use it alongside whatever else you buy. Stronger on analysis than on drilling.

If you are working toward AP, a diploma, or a degree

Kostka & Payne, Tonal Harmony

The most widely assigned undergraduate harmony textbook in North America, and the closest match to AP Music Theory content. Systematic, exercise-heavy, and thorough on part writing. Older editions are much cheaper and differ little in substance.

Aldwell & Schachter, Harmony and Voice Leading

Deeper and more demanding than Kostka, and Schenkerian in outlook. It explains why voice-leading rules exist rather than listing them, which makes it the better book for someone who wants understanding rather than a pass. Harder going as a first text.

Piston, Harmony

Older, drier, and still one of the clearest accounts of harmonic function in print. Worth owning as a reference even if you learn from something else.

For ear training specifically

Karpinski, Manual for Ear Training and Sight Singing

The standard text, and the one that treats aural skills as a subject with its own pedagogy rather than an afterthought. If you are serious about ear training, this is the book. Pair it with the accompanying anthology.

For jazz and popular music

Levine, The Jazz Theory Book

Comprehensive on chord-scale theory, voicings, and reharmonisation. Assumes you can already read and know your basic harmony, so it is a second book rather than a first.

How to actually use a theory book

1. Do the exercises. Reading a theory book without writing is like reading about swimming. This is the single reason most self-teachers stall.
2. Play everything. Every example, at an instrument, however slowly.
3. Sing everything. Especially bass lines. See solfege.
4. Buy an older edition. Harmony has not changed since 1900. A used previous edition costs a fraction and differs mainly in the exercise numbering.
5. One book at a time. Collecting theory books is a well-documented substitute for studying theory.
