Yeah this page was fun!
Time to blow some dust off my keyboard
Nice idea. Only a bit strange though that they have left many common chords out from the table (they have for example half diminished seventh, but not a full dimished, and where is the standard dim and aug chords?)
yes it might be useful but I would like to have also an offline version.
it´s much easier to access it then.
