# Open Chords

Open chords tend to sound \"richer\" than corresponding barre chords due
to the fact that open strings resonate freely without any hindrance.
Open chords typically sustain longer than their barre chord equivalent.
An open chord is any chord that has one or more strings sounded without
being fretted. Guitarists tend to use this name to refer to the chords
that contain open strings that are played in the first position (first
four frets).

down in pitch along a string to give different keys.

## Open seventh chords

Seventh chords, strictly speaking from a music theory perspective, means
any seventh chord, including major, minor, dominant seventh, diminished
and so on. In a beginning guitar context, however, \"seventh chord\"
often means a dominant seventh chord, which is a major triad with a
flatted seventh. The G dominant seventh chord, or G7 chord, is the notes
G, B, D and F.
