A7 Chord on Banjo
A Dominant 7th is A, C#, E, G — the 1-3-5-b7 pattern of a seventh chord. Here is the shape, the audio, and what usually goes wrong.
Good news: A7 has an open shape on banjo, so you can play it without barring anything. Start there and work up the neck later.
Start here — Standard A7
Open shape — open strings ring right through it and there is nothing to barre. If you only learn one, learn this one.
What beginners get wrong
Moving in and out of it
The shape above: Standard A7 — open position, so several strings ring unfretted — barred at fret 2.
Listening: each shape above has its own play button, and each one plays the notes that shape actually produces — not a generic triad.
