ChordSpace is a virtual MIDI instrument (VSTi) designed for exploring music theory. A map of harmonic space provides a palette of 226 chords per key for song writers to play with, based upon jazz harmonic theory. Sounds can be generated using the mouse or a velocity sensitive MIDI keyboard and there’s inbuilt control over MIDI note channel assignments.
Complete chord voicings can be heard by clicking the mouse on chord symbols grouped in hexagrams. The chords can also be arpeggiated automatically using a selection of patterns. Related chord groups are arranged around a central key wheel (circle of fifths), making it simple to view a map of natural chord relationships in any key.
The website provides a good basic guide to jazz chord theory using the software and links to other music resources.
ChordSpace is an inspirational and educational tool, free to download (2.12Mb), it was developed using Synthedit.
