Musical harmony analysis tool (musical keys, chords and harmonies)
This plugin helps in musical harmony analysis. To use the plugin, you should select musical notes from a musical score. The selected note names will appear in the plugin where you can search them for musical keys, chords and harmonies.
When you want to determine a musical chord or harmony, you should select the musical notes that imply this musical chord or harmony. You can select the chord tones and nonchord tones together and then exclude the nonchord tones in the plugin.
The plugin shows docked in the left side panel of the MuseScore window. It adjusts itself to the available screen space but you should probably enlarge the left side panel for the best results,
