Where can I find a good on-line chord dictionary or list of chords?
Most chord dictionaries and chord lists I have come across cover only basic chords and are not much use for finding shapes for slightly more unusual chords (D/F#, F#7add4, Bm11 …). This page offers help with chord shapes, points out the common problems with chord dictionaries, and suggests a method for finding shapes for any chord shape you are interested in.
