Piano Companion is a flexible chord/scale dictionary with user libraries and reverse mode. Piano Companion allows you to find a chord or scale by its name. If you don't remember what's the name of a chord/scale, it helps you to find it by keys. Piano Companion shows chord/scale notes, degrees, fingering for both hands in major and minor scales. You can listen how a scale or chord sounds. You can see the list of compatible chords in the selected scale.
