ChordWeaver!

ChordWeaver is a musical composition aid based on modern 5-part tonal harmony used extensively in symphonic music, film scores, jazz chord changes, contemporary songwriting, game soundtracks and electronic/synthesizer compositions with real time audio feedback. ChordWeaver extensively uses techniques like altered chords (or unresolved appogiaturas), parallel ninths, giant steps, tritone substitutions, bi-tonal ambiguity. They reflect the actual use of these chord progressions and resolutions by these composers and are not simply based on purely theoretical considerations.
