Shape and spelling
Chord finder
Pick G and minor and the page should show G, Bb, D, plus a grip you can actually fret. Open chords are listed when a familiar shape exists: C, G, D, A, E, the common sevenths and suspended forms. Everything else moves an E-form or an A-form barre so the root sits on the sixth or fifth string. Muted strings are marked with an x. Open strings are rings.
What the intervals are
Major is root, major third, fifth. Minor lowers the third. Dominant 7 adds a minor seventh. Major 7 adds a major seventh. Sus2 and sus4 replace the third with a second or a fourth. Dim is root, minor third, flat fifth. Aug is root, major third, sharp fifth. The note names follow flats when the root is F or already flat, and sharps otherwise. You are looking at pitch classes, so the same name can appear in more than one octave on the neck.
Standard tuning only
The pictures assume EADGBE. A capo does not move these diagrams; you still fret the shape and the sounding chord is higher. If you are in drop D, the low-string notes in an E-form barre are no longer what the picture says. Use the finder for standard, then retune.
Questions
- Why two diagrams?
- The open C is not the same grip as a C barre at the eighth fret, and both are C major. The page shows the ones it can draw honestly, not every inversion.
- Where is the slash chord?
- Bass notes under a slash belong in the transposer, which will move D/F# as two notes. This page builds one chord quality.
