The Guitar, Shape by Shape

Every page here speaks guitar as a first language: open-versus-barre choices, movable shapes, and the neck geography that links them — for six strings and the whole extended family.

Guitar Chords The CAGED System Scales Tuner

Free, playable chord and scale references for all seven members of the guitar family — every diagram voiced on the neck it names, with the CAGED links that turn five familiar grips into the whole fretboard.

Choose Your Instrument

Seven necks, one geography: EADGBE runs in fourths with a single kink at G–B, the 7- and 8-string extend that grid downward, the 12-string doubles it into courses — and three relatives rewrite the rules on purpose.

Guitar

  • Tuned E–A–D–G–B–E
  • Fourths with one kink — the G–B third
  • Home of the five CAGED shapes

12-String Guitar

  • Tuned E–A–D–G–B–E, six courses
  • Lower four courses doubled in octaves
  • Six-string fingerings, unchanged

7-String Guitar

  • Tuned B–E–A–D–G–B–E
  • A low B under the standard six
  • The same grid, one string deeper

8-String Guitar

  • Tuned F#–B–E–A–D–G–B–E
  • Two strings below the standard six
  • The grid at its deepest reach

Tenor Guitar

  • Tuned C–G–D–A in fifths
  • 4 strings — a different system, not a subset
  • Shares its shapes with the tenor banjo

Terz Guitar

  • Tuned G–C–F–A#–D–G
  • Standard shapes, a minor third higher
  • Guitar’s own interval pattern throughout

Resonator

  • Tuned G–B–D–G–B–D — open G
  • The open strings sound a G major chord
  • Voicings computed for this tuning, never borrowed

What Lives Here

Chords

Every key and quality as neck shapes — open forms where they exist, movable grips sorted lowest position first.

Scales

Position boxes with the roots flagged, drawn to overlap so one box always hands you the next.

Fretboard Explorer

Light up any set of notes across the neck and watch the geography connect them.

Progressions

Each key’s chord family as grips ready under the hand, playable straight through.

Exercises

Daily picking and fretting drills generated from the neck itself, with tab and sound built in.

The CAGED System

Five open chords you already know, revealed as the five movable shapes that chain up the whole neck.

Lead Boxes

The five pentatonic positions derived fret by fret, with every overlap verified in CI.

Alternate Tunings

Drop D, DADGAD, and open G as computed retune maps — which strings move, and what the neck now spells.

Capo by Key

Start from the key the song is in: where the capo goes, and which shape system you land in when it clamps.

Gear, Explained

Amps, pedals, pickups, and strings as a signal chain, not a catalog.

Coming Back?

The honest audit of what survived the years off — and a first week that works.

Chord of the Day

One chord each morning in all five CAGED forms — the same network-wide pick every Warrior site agrees on.

Free Tools

Tuner, metronome, and theme builder — free, in the browser, no sign-up.

How It Works

1

Pick Your Neck

Six-string to eight-string, tenor to resonator — every reference page is drawn for the neck it names: string count, tuning, and all.

2

Learn the Shape

Diagrams speak the fretboard’s own language: open versus movable forms, tones named per string, and the one G–B kink that explains the grid.

3

Move It Everywhere

CAGED links chain each grip up the neck, playback lets your ear vet a shape before your fingers commit, and the daily drills make it stick.

The Shape-System Home

Guitar Warrior is the Warrior Network’s deep home for the guitar family. The premise is simple: the guitar is best learned as a shape system, because the EADGBE grid is regular in fourths with exactly one kink — the G–B major third — and that single fact is why chords come in open and movable forms, why scale boxes tile the neck, and why one grip serves twelve keys. Every chord, scale, drill, and guide on these pages is built from that geometry, with playback everywhere so your ear vets a shape before your fingers learn it.

The Questions Guitarists Ask

The full FAQ has the longer list.

Are these real guitar chord shapes or auto-generated grids?
Every diagram is voiced on the tuning of the neck it appears on, open and barre forms alike, and the CAGED pages are derived from the same voicing library the chord pages use — then re-verified in CI, fret by fret.
Do the 7-string and 8-string get real pages?
Yes. Both extended necks carry full chord, scale, progression, and exercise references with the low B — and the 8-string’s F# — drawn in every diagram, not bolted onto a six-string chart.
What makes the tenor, terz, and resonator different here?
Each one breaks a different rule. The tenor guitar swaps the system for four strings in fifths (C–G–D–A); the terz fingers standard shapes but sounds a minor third higher; the resonator lives in open G, with voicings computed for that tuning rather than borrowed from EADGBE.
Do I need all five CAGED shapes before anything makes sense?
No — but the neck rewards you when you have them. Each shape is one open chord turned movable, and the CAGED guide derives all five from the chord library and links them fret by fret so you can add one at a time.
Does any of this cost money?
No. Every reference page, guide, drill, and tool on Guitar Warrior is free with no ads and no account — your theme and left-handed settings live in your own browser.
