MIntavalla

MIntavalla consists of an Interval circle and two keyboards underneath:
an upper melody- and a lower harmony keyboard.
It illustrates musical events by analysing and specifically colouring chord intervals (lower harmony keyboard) and melody intervals (upper melody keyboard) in realtime:
- chord intervals related to the tonal center established by the first chord root being played.
- melody intervals related to the chord root currently being played (upper melody keyboard).
- the interval circle above the keyboards highlights the chord currently being played (here: G minor) and also records the chord interval levels of all chords relative to the tonal center (outer interval ring).
- the (adjustable) colors represent the absolute semitone distance of the chord and melody notes to the respective tonal center or chord root.

Mintavalla is a 64Bit Windows program. It works purely with realtime midi data.
