Learn harmony that goes beyond the tonal tradition. Start with deriving chords and melodies from non-diatonic scales like the whole tone and Phrygian dominant. Then move into common dissonant chords like those built from stacked 2nds, atonal chords with semitone dissonances, and polychords that include atonal chords. Finally, learn how to write 12-tone rows with musical character and explore a range of modernist techniques like composing with clusters, extreme registers, and writing aleatoric music to give your music an eerie and foreboding sound.
