The relationship between secundal harmony and symmetrical scales is a fascinating area of study in music composition. Understanding how these elements interact can deepen our appreciation of modern and classical music alike.
What Is Secundal Harmony?
Secundal harmony refers to chords built on the interval of the second, such as seconds and their extensions. Unlike traditional tertian harmony, which is based on stacking thirds, secundal harmony emphasizes intervals of seconds, creating a distinctive sound.
Understanding Symmetrical Scales
Symmetrical scales are scales that divide the octave into equal parts. Examples include the whole tone scale, which divides the octave into six equal steps, and the octatonic scale, which alternates whole and half steps. These scales are often used in jazz, modern classical, and experimental music.
The Connection Between the Two
Symmetrical scales provide a unique harmonic palette that complements secundal harmony. Because these scales contain many seconds, they naturally support the stacking of seconds to form chords. This creates a sound that is both innovative and cohesive, often used to evoke tension or ambiguity in a composition.
Examples in Composition
- Debussy’s use of the whole tone scale: creates a dreamlike atmosphere with prominent secundal harmonies.
- Stravinsky’s octatonic scale: provides a basis for complex, modern harmonies that often emphasize seconds.
- Contemporary jazz improvisation: frequently employs symmetrical scales to build chords based on seconds.
These examples demonstrate how composers leverage the symmetrical nature of scales to craft harmonies centered around seconds, enriching the texture and emotional impact of their music.
Conclusion
The interplay between secundal harmony and symmetrical scales opens new avenues for musical exploration. By understanding their relationship, composers and students can create more innovative and expressive works that challenge traditional harmonic concepts.
