Open A Minor 7 Tuning

E·A·E·G·C·E

Tonal centre A minor 7 — the open chord is already a minor seventh Also called Open Am7, EAEGCE Difficulty Very easy — two strings move

Open A minor 7 raises the 4th string a whole step from D to E and the 2nd string a semitone from B to C, and leaves the rest at standard pitch. The open strings then spell an A minor seventh — E, A, E, G, C, E — a full, mellow chord with nothing fretted.

It is Open A minor with the 3rd string left at G instead of raised to A, which turns the open Am into an Am7. Only two strings differ from standard, so it is one of the fastest alternate tunings to reach and leave, and a lot of standard shapes still read. Good for soft, modal, open-string writing centred on A minor.

How is Open A minor 7 different from Open A minor?
Open A minor raises the 3rd string to A for a plain Am chord. Open A minor 7 leaves the 3rd string at G, so the open chord is an Am7 instead.
Is Open A minor 7 easy to tune to?
Yes — only two strings move, and neither by much, so it is one of the quickest alternate tunings to reach and to undo.
Do my normal chords work in Open A minor 7?
Many do. Four strings stay at standard pitch, so shapes that do not lean on the 4th or 2nd string transfer directly; others need a small adjustment.
Can I use a capo in Open A minor 7?
Yes — a capo raises the whole tuning to a higher key while keeping the open minor-seventh sound. Open—Shape recalculates every voicing for the capo position.
