Symmetric Scales
Mathematical perfection in music: scales built on repeating interval patterns.
Octatonic (Diminished) Scale
A symmetrical 8-note scale built by alternating Whole and Half steps. Often used by composers like Stravinsky and Bartók for its unstable, versatile nature.
Augmented Scale
A symmetrical hexatonic (6-note) scale built by alternating 3 Half Steps and 1 Half Step. Common in late 19th/20th-century music and modern Jazz for its "outside", floating sound.
3 Half Steps - 1 Half Step (repeating)
1 - b3 - 3 - 5 - #5 - 7
Composition Insight
Symmetric scales like the Octatonic and Augmented provide mathematical perfection and ambiguity. The Octatonic scale's alternating intervals create versatile tension perfect for modern classical and film music. The Augmented scale's floating quality adds an "outside," unstable character ideal for Jazz and experimental compositions. Use these scales to escape traditional tonality while maintaining structural coherence.
