Guitar fact
Capo
Standard tuning. Position 1 has the root note on the low E string, like most charts. Positions 2 to 5 follow up the neck. Orange dots are the root. The five boxes follow the CAGED system, so a scale and its relative scale share the same boxes.
Tap a string to hear it, then tune yours to match.

How do I read a chord?
Finger (1 = index)
Root note
Open or muted string
Barre
- Tap any chord to hear it.
- A number like 3fr beside the top fret means the shape sits higher up the neck.
What notes are in a chord?
- A chord is a few notes played together. The basic three are the root (the chord's name), the 3rd and the 5th.
- C major is C, E and G. Lower the 3rd by a half step and you get C minor: C, E♭, G.
- Add a 7th on top and you get a 7th chord, like C7: C, E, G, B♭.
- Every section on the Chords tab shows its recipe at the top, like 1 · 3 · 5. The 1 is the root.
How does the tuner work?
- Open the Tuner tab, tap Start live tuner and allow the mic.
- Pluck one string. The needle shows flat or sharp.
- Needle left: tighten. Needle right: loosen. Green means in tune.
- Start with the low E and work up.
- Pro tip: a 12th-fret harmonic counts as the same string.
How do I use the Scales tab?
- Pick a key and a scale. The notes appear underneath.
- Tap a position, 1 to 5, to see one box on the neck. Position 1 has the root on the low E string. Orange dots are the root.
- Press Play to hear it up and back down.
What does a capo do?
Capo
- A capo clamps across the neck and raises every string by the same amount, so the same shapes sound higher.
- On the Chords tab, tap Capo and pick a fret.
- The big name is what you hear. The small orange name is the shape your fingers make.
