Only difference between Chords and Chords+ page is in way how chords are generated.Chord page
contains chord shapes which are manually entered in database.Chords+ page contains chords
shapes generated by a computer algorithm.For that reason Chords+ page contains much more
variations for every chord type.Also,for same reason Chords+ page contains many chord shapes
which are unusual and strange in both-its shape and its sound. Algorithm used for generating chords is intelligent in sense that chords which cannot be played by
real man are not included.All chords can be played with 4 fingers but some of them are harder to
master.
For example here are two variations on Cmaj7 chord,one common shape from Chords page,and
second, a little unusual shape from Chords+ page.
