Chord & FretC/A on guitar
On the guitar, six strings give the chord room to breathe — some positions use them all, others ask you to mute the lowest ones. In this C/A voicing the bass is A and the shape runs from fret 1 to 2, ringing 3 open strings. Its hollow wooden body gives every chord a warm, natural ring that blooms and fades on its own.
Notes in C/A: A – C – E – GFormula: 1 – 3 – 5 / 13In the formula, the numbers count steps of the major scale starting from the note that names the chord; "b" lowers a half step, "#" raises one — and a slash names the bass note.
Where to use it: The crossing between a major key and its relative minor, and descending bass lines generally.

In Chord & Fret, you hear every shape strummed string by string, in the instrument's own voice; open every variation on the neck, grouped by bass note; and change the tuning — the shape rewrites itself.
