Notes

What notes are in B Diminished?

The B Diminished chord has 3 different notes: B, D, F. Two minor thirds stacked; the diminished fifth (6 half steps above B) gives it its tension. A guitar chord rarely has as many strings as notes, so shapes double some of them: every shape here leaves at least one string unplayed - watch the x marks. Mute the strings marked x with the side of a fretting finger, so that only the chord rings.
