Land on a root

Square markers are the root of your selected pattern. Play a short phrase, then finish on a root and listen for its sense of arrival.

Reading and playing the diagram

The thin, high E string is at the top; the thick, low E string is at the bottom. Numbers above the neck identify frets. The open-string column appears only in ranges that start at Open. Every marker is a note in your selected pattern, not a suggested fingering.

Choose Note names or Intervals to change the labels without changing the notes. Desktop layouts offer twelve-fret ranges; mobile layouts offer six-fret close-ups that automatically fit the screen. Whole neck is available on both and fits open strings through fret 24 without sideways scrolling. When resizing between layouts, Whole neck stays selected; other ranges move to the closest available range by midpoint.

When space is tight, note labels are omitted and fret numbers are simplified to avoid crowding. Choose a close-up for readable labels and easier tapping. Labels return automatically when there is enough room. Detailed desktop views can scroll sideways when needed. Keyboard: Tab into the diagram, use arrows to move between notes, and press Enter or Space to play. Home and End move to the first and last visible note on that string.

What the CAGED regions mean

For verified compatible patterns, CAGED regions use the same-root major or minor pentatonic framework automatically. Major, Lydian, and Mixolydian use major pentatonic; Dorian, Phrygian, and natural minor use minor pentatonic. Pentatonic and blues patterns use their corresponding framework.

Major and minor triads also offer CAGED regions. Major 7th and dominant 7th arpeggios use major chord-shape references; minor 7th and minor major 7th use minor chord-shape references. These reuse the verified region geometry as chord-tone anchors, not exact arpeggio fingerings. Only the selected chord tones are displayed; pentatonic notes are not added.

C shape, A shape, G shape, E shape, and D shape refer to movable chord-shape families, not the names of five different keys. The same labels apply to major and minor references; the selected pattern supplies that context. The colored regions are a reference map, not rigid fingering boxes: shapes overlap, and a fingering can reach beyond a boundary.

Highlight pentatonic notes is offered only when the selected pattern contains the complete matching pentatonic plus other tones. It is not offered for triads or these seventh arpeggios. Patterns without a verified CAGED framework do not offer region controls; no outside notes are added.

Exploring the full catalog

Pattern families include modes, pentatonics, blues, minor-scale variants, symmetric scales, triads, and arpeggios. Extended arpeggios show pitch classes across the neck: 9, 11, and 13 describe chord functions, not a required octave or playing order. Melodic minor uses the ascending form in both directions.

Each pattern has a sound description below the diagram, with characteristic intervals to listen for. Words such as bright, dark, or floating are listening guides, not fixed emotions: the tonal center, accompanying harmony, register, rhythm, and phrasing all affect the result. Establish the root and compare patterns on that same root to hear their differences. Individual note playback is not an automatic performance of a scale or chord.
