The whole tone scale is a unique musical scale that consists entirely of whole steps, creating a symmetrical and ambiguous sound. Its distinctive quality makes it a fascinating tool for composers and musicians seeking to add color and complexity to their harmonies.
Understanding the Whole Tone Scale
The whole tone scale contains six notes, each separated by a whole step. For example, starting on C, the scale would be: C, D, E, F♯, G♯, A♯, and then back to C. Because of its symmetrical structure, it lacks the traditional tonal center, resulting in a dreamlike or surreal sound.
Why Combine the Whole Tone Scale with Other Scales?
While the whole tone scale offers a distinct sound, blending it with other scales can create richer, more complex harmonies. This approach allows composers to maintain the scale’s unique qualities while introducing familiar tonal elements, enhancing emotional expression and musical interest.
Combining with Major and Minor Scales
One common technique is to use the whole tone scale as a coloristic device alongside major or minor scales. For instance, a melody might primarily use a C major scale, but incorporate whole tone scale passages on certain chords to evoke a sense of ambiguity or tension.
Blending with Modal Scales
Modal scales, such as Dorian or Phrygian, can be combined with the whole tone scale to produce exotic and intriguing harmonies. For example, shifting between a D Dorian mode and a D whole tone scale can generate a shimmering, otherworldly effect.
Practical Techniques for Combining Scales
Musicians can experiment with various methods to blend the whole tone scale with other scales:
- Switching between scales within a phrase to highlight different colors.
- Using chromatic passing tones derived from the whole tone scale to connect diatonic notes.
- Overlaying whole tone scale motifs over traditional harmonic progressions.
Examples in Music History
Many 20th-century composers, such as Claude Debussy and Olivier Messiaen, employed the whole tone scale to evoke dreamlike atmospheres. They often combined it with other scales to deepen the harmonic palette and create innovative textures.
Conclusion
Combining the whole tone scale with other scales opens up a world of creative possibilities. Whether used subtly or prominently, these combinations can produce rich, evocative harmonies that captivate listeners and expand the expressive range of musical composition.
