Hear one new relationship.
Begin with a short example. We introduce one main idea, not a whole page of unrelated facts.
FREE GUITAR MUSIC THEORY
You can play chords, riffs and scale patterns. But do you know why those notes work together? Build real musical understanding—one small, playable idea at a time.
The same note can mean something different when the chord changes beneath it.
Listen first, then name the sound.
Use clear, clickable fretboard maps.
Change a note and explain why.
BUILT AROUND UNDERSTANDING
Tabs can tell you where to put your fingers. Here, you'll also learn what those notes are, how they relate to the chords, and what happens when you change them.
Begin with a short example. We introduce one main idea, not a whole page of unrelated facts.
Fretboard diagrams, chord notes and warm electric-guitar playback connect theory to playing.
Strum a progression, follow a phrase, then make a deliberate musical change of your own.
START SMALL
Every path leads back into the same course. Start from the beginning, or try a topic that already feels familiar.
No need to start guitar again. Give familiar strings and shapes musical names.
Understand the instrument 02Hear how a single note turns major into minor—and find that change under your fingers.
Hear the change 03Build from a small note choice to a melody that follows the harmony.
Make a musical choiceLEARN BY LISTENING
Hear the music, follow the chord changes, and gradually understand each note in a real phrase. Even the complete studies are included in the free course.
Explore an explained soloTHE COMPLETE FREE COURSE
Explore all 12 parts, from notes and rhythm to chord construction, pentatonics, modes and, later, blues. Work through one small idea at a time.
Open one part at a time. Later topics can wait until their foundations feel familiar.
Make the guitar you already play less mysterious. Work on one string before opening up the whole neck.
Build a dependable pulse, then add held notes, silence, subdivision and a simple strum. Keep the fretting easy.
Learn a few useful intervals carefully. Separate letter counting from fret movement before using chord formulas.
Understand C major in a small space, then transfer the construction method to G. Make a little music before collecting positions.
Build major and minor triads first. Decode familiar grips, then gradually introduce bass notes, inversions and the other triad qualities.
Build one chord family, strum it, find simple destinations, and join tiny phrases. The full study arrives only after its ingredients are familiar.
Establish natural minor as its own sound. Separate parallel from relative comparisons, then build a minor melody in small steps.
Learn maj7, m7 and dominant 7 separately before comparing their diatonic roles. Use simple voicings and melodic targets.
Derive the five-note collections from understood scales. Build phrases, learn precise expressive targets and finish with an explained rock solo.
Use CAGED as chord landmarks, then relocate an understood phrase. Three-notes-per-string is an optional route, not another theory system.
Keep a tonic fixed and change one characteristic interval. Apply Dorian and Mixolydian first; explore the remaining modes in separate optional lessons.
Now introduce the deliberate mixture: twelve-bar form, dominant-seventh harmony, two blues scales and expressive pitches. Finish by explaining your own musical choices.

A FEW GOOD QUESTIONS
There's no test to enter and no schedule to keep up with. These guides explain how to get the most from each short lesson.
This free course is for guitarists who can already play some chords, tabs or patterns and want to understand what those movements mean. No previous theory qualification or reading fluency is required. A standard-tuned six-string guitar is the reference instrument. The goal is not to collect every diagram: it is to connect what you play, hear and understand.
Use one lesson per sitting as a starting point, and repeat it when necessary. A lesson may take a few minutes to read but more than one practice session to settle. There is no imposed daily deadline and no need to complete the entire roadmap before enjoying a short musical example.
Each lesson has one principal discovery, a worked example, a small guided task, a question with an explained answer, and a readiness statement. Answer panels are hidden until requested in the reader. Practice-only stops introduce no compulsory new theory. Optional extensions can be skipped without losing the core route.
Read and play in separate passes. First listen to the example. Next locate the notes. Later inspect their labels and explain the relationship. Do not try to process fret numbers, note names, scale degrees, chord roles and rhythm all at once. The detailed solo tables are reference material to reveal one bar at a time.
The entire concept course and the nine included studies can be used for free. You can practise without creating an account.
A gentle practice session can begin with a minute or two recalling the last idea, followed by one new explanation. Listen once without playing. Try the worked example slowly, then attempt the independent question. Check its answer and write one observation. Finish before you feel obliged to cram in the next topic.
After two or three lessons, return to an earlier task in a different order. Reconstruct a note from a known landmark, find a chord tone without running a full scale, or clap a rhythm before fretting it. The practice-stop lessons provide longer pauses for consolidation.
A readiness check is not a speed test. You may use a reference map when reconstructing the relationship. Before moving on, aim to demonstrate it after a short break and explain it in ordinary words. An experienced player can skip a familiar lesson after doing its check, but should not assume that physical fluency proves the theoretical connection.
Your notes need only four headings: what I tried; what I can now explain; what still feels unclear; the small task I will return to. No recordings, uploads or lengthy practice diary are required.
Standard tuning, low to high: E2–A2–D3–G3–B3–E4. String 1 is high E, string 6 low E. Tab has high E at the top. A 0 means an open string; x means omit the string. Scientific pitch numbers such as C4 distinguish sounding octaves; they are not fret numbers. A note’s displayed guitar position is one verified option, not the only place to play it.
Rhythmic durations in the study tables are quarter-note beats: 1 = one beat, 0.5 = half a beat, 2 = two beats. All main studies are in 4/4. Every recording begins with a four-beat count-in. Slower recordings are rendered at 50 BPM without lowering the pitch. Backing recordings repeat the stated form three times, with one count-in at the very beginning; there is no extra count-in between rounds.
In the detailed study tables, degree labels use the parallel-major interval reference: in A natural minor, C is b3 and F is b6 above A. Their ordinal positions in the natural-minor list are third and sixth. Chord-role labels use the current chord root instead. Major-key Roman numerals use I–ii–iii–IV–V–vi–vii°. Natural-minor numerals are written i–ii°–bIII–iv–v–bVI–bVII with the parallel-major root reference made explicit.
Sampled-guitar playback is programmed from recordings of individual notes, not a human playing each complete passage. Basic study tracks use picked-note articulation; pitch targets for slides, hammer-ons, pull-offs, bends and vibrato are taught separately. Audio timbre is an aid to learning, not evidence of a filmed hand technique. Keep listening volume comfortable and stop physical exercises that hurt.
