In music theory and harmonic analysis, a synthetic chord is a made-up or non-traditional (synthetic) chord (collection of pitches) which cannot be analyzed in terms of traditional harmonic structures, such as the triad or seventh chord. — Sitsky (1994), However, synthetic chords originated not with Roslavets but with musicologist Sabaneev and his study of composer Scriabin's Prometheus published in 1910. See: Mystic chord. Some synthetic chords may be analyzed as traditional chords, including the Prometheus chord, which may be analyzed as an altered dominant chord.
