These are note locations, not generated TAB. You choose where and how to play them.

Prototype: pitch detection is approximate. Hum one clear note at a time. This is meant to get you into the ballpark, then your ear and hands finish the idea.

Music Theory

Learn why notes and chords work together, then try it yourself. Start with intervals, build scales and triads, and discover the chords in a key.

Using your current learning key and mode

Intervals: the distance between notes

An interval is simply the distance between two notes. The easiest way to measure that distance on guitar or bass is to count frets on the same string.

Half step = move 1 fret. If you play the 3rd fret, move to the 4th fret on the same string. That is one half step.
Whole step = move 2 frets. If you play the 3rd fret, move to the 5th fret on the same string. That is one whole step.
For example, E to F is a half step; C to D is a whole step. You may also hear “semitone” for half step and “tone” for whole step.

Scales are interval recipes

Scales are built by moving between notes in a pattern. Whole step (W) means move 2 frets on the same string. Half step (H) means move 1 fret. For example, starting at the 3rd fret, a whole step takes you to the 5th fret; a half step takes you to the 4th fret.

A major scale uses W – W – H – W – W – W – H. Just follow those fret distances in order. Natural minor uses W – H – W – W – H – W – W.

Modes change the intervals measured from the root, changing which notes create tension, brightness, or a darker sound. The same seven notes can also make different modes when a different note feels like home. Explore each mode below to see what changes and when you might use it.

The displayed note spellings use sharps for enharmonic pitches. In written theory, some keys are more naturally spelled with flats.

Build a triad: root, third, fifth

Triads are three-note chords. R means root. Major = R–3–5; minor = R–♭3–5; diminished = R–♭3–♭5; augmented = R–3–♯5. The third determines major versus minor; changing the fifth adds a different character.

Try changing only the chord quality and watch which note moves. That's why the third matters so much.

Chords that belong to a key

Build a triad on each note of a seven-note scale by taking every other scale note: R–3–5 from each starting scale note, then the next scale note, and so on. The chord qualities emerge from the scale's intervals.

Pentatonic scales contain five notes, so they don't generate the same seven diatonic triads. Choose a seven-note mode here.

CAGED System

See major and minor chord forms with nearby soloing notes. Gold = root, blue = chord tone, teal = scale note.

CAGED shapes are based on standard guitar tuning. Some chord positions extend beyond fret 12; those frets are not displayed. Some minor forms use partial voicings or muted strings.
