ChordCompanion is a chord utility that is powerful yet simple to use.
ChordCompanion lets the user design chords on a virtual guitar neck. It can analyze chords and suggest names for them, or it can display chord formation from chord names.
All this is done using a musical theory engine, not a database of known chords. Therefore, there are no limitations on chord formations that can be processed or suggested.
ChordCompanion runs on 68k or PPC Macintoshes (two separate programs - keep the one you need - saves space on your hard disk). Requires system 7.0 or higher.
