Mortenulstrup's List: Musik

You can either use single-finger triggering in the style of home keyboards (one finger for a major, any white key to the left for a seventh, any black key to the left for a minor or any black and white key to the left for a major seventh) or you can hold down all the correct notes as a block chord. Of course there can be an ambiguity if you play a three-note chord comprising one white note and one black note below the top note, as Virtual Guitarist seems to have no way of deciding whether you intend this to be an 'easy' chord

As a rule, it's safest to use easy chords for majors, minors and minor sevenths, while using full fingering for other chord types.
