Open mandolin chords are chords formed on the neck of the mandolin utilizing open strings. The following is by no means a comprehensive charting of the open chords available on the mandolin. However, there are enough major chords here, as well as minors and sevenths, to play a lot of tunes. Especially in the common keys of C, G, D and A. When I add more, I’ll probably have to group them better.
You’ll notice with the first couple of E-chords that you don’t want the 4th string (the low G) to sound, so you either don’t hit it, or mute it with the fleshy part of your thumb. For the first E-chord and the first A-chord, – if you can’t fret both strings with one finger, then use two. The finger numberings are suggestions based on attack, strength and economy of movement.
