Microtonal electronic music represents one of the most exciting frontiers in modern sound design and composition. By moving beyond the standard twelve-tone equal temperament (12-TET) that has dominated Western music for centuries, producers can access an infinite palette of pitches and intervals. This exploration allows for the creation of unique moods, cultural authenticities, and otherworldly textures that are simply impossible to achieve with traditional tuning. Whether you are looking to replicate ancient scales or invent entirely new harmonic landscapes, understanding the mechanics of microtonality is essential for any forward-thinking electronic artist.
Understanding the Basics of Microtonality
At its core, microtonal electronic music involves using intervals smaller than a semitone. While a standard piano keyboard divides an octave into twelve equal parts, microtonal systems can divide that same space into 19, 22, 31, or even hundreds of distinct steps. These systems are often referred to as xenharmonic or alternative tuning scales.
The shift toward microtonal electronic music is driven by a desire for greater emotional resonance. Many artists find that 12-TET feels “sterile” or mathematically compromised because it slightly detunes intervals to make them uniform across all keys. Microtonality allows for “Just Intonation,” where intervals are based on whole-number ratios, resulting in chords that sound incredibly pure and resonant.
Common Tuning Systems in Electronic Production
When diving into microtonal electronic music, you will encounter several foundational tuning systems. Each offers a different aesthetic and harmonic potential. Some of the most popular include:
- Just Intonation (JI): Based on the natural harmonic series, providing exceptionally clean and stable intervals.
- Equal Temperaments (EDO/TET): Dividing the octave into equal parts other than 12, such as 15-EDO for a bluesy feel or 22-EDO for complex melodic possibilities.
- Bohlen-Pierce Scale: An alternative scale that divides a perfect twelfth into 13 steps, completely bypassing the traditional octave.
- Quarter Tones: Frequently used in Middle Eastern music, these involve dividing the standard semitone in half.
Essential Tools for Microtonal Electronic Music
The rise of digital technology has made producing microtonal electronic music more accessible than ever before. In the past, hardware synthesizers had to be manually modified, but modern software provides flexible solutions for retuning. Most digital audio workstations (DAWs) and VST instruments now support various methods of pitch manipulation.
One of the most critical formats for microtonal electronic music is the Scala file (.scl). Scala is a powerful software tool used for creating and managing musical scales. Most high-end software synthesizers, such as Xfer Serum, Vital, and u-he Zebra, allow users to import .scl files to instantly remap their oscillators to new tuning systems.
Hardware and Controllers
Traditional MIDI keyboards can be a hurdle when performing microtonal electronic music because their physical layout is designed for 12-TET. To overcome this, many producers use isomorphic controllers. These devices, like the Lumatone or the LinnStrument, use a grid of buttons that makes it easier to visualize and play unconventional scales without the bias of a piano-style layout.
Techniques for Composing with Microtones
Starting with microtonal electronic music can be overwhelming if you attempt to use too many notes at once. A helpful approach is to start with a “limited” microtonal scale. For example, try using a 5-note or 7-note scale derived from Just Intonation. This allows you to hear the difference in resonance without getting lost in a sea of unfamiliar pitches.
Another effective technique is to use microtonality for texture and pads. Because microtonal intervals can create unique “beating” effects when frequencies are close together, they are perfect for creating evolving, organic soundscapes. This is a staple technique in ambient and experimental microtonal electronic music, where the focus is on the physical sensation of the sound rather than traditional melody.
Integrating Microtones into Modern Genres
Microtonal electronic music is not limited to experimental or academic circles. It is increasingly found in techno, house, and bass music. Producers use microtonal leads to create a sense of tension and unease that stands out in a club environment. By subtly detuning certain notes in a sequence, you can create a “humanized” or “alien” feel that captures the listener’s attention.
The Benefits of Microtonal Electronic Music
Adopting microtonality offers several competitive advantages for music producers. In a crowded market, having a unique sonic signature is vital. Microtonal electronic music provides a way to sound different from the millions of tracks produced using standard tuning. It forces you to listen more closely to the relationships between frequencies, which ultimately improves your overall ear training and sound design skills.
Furthermore, microtonality allows for better cultural representation. Electronic music is a global phenomenon, and many musical traditions around the world do not use 12-TET. By mastering microtonal tools, producers can collaborate more effectively with traditional musicians from various cultures, blending ancient scales with modern synthesis.
Challenges and How to Overcome Them
The primary challenge in microtonal electronic music is the learning curve associated with music theory and software configuration. It can be frustrating when your favorite plugin does not support microtuning. However, tools like MTS-ESP by OddSound have revolutionized the workflow. This plugin acts as a master tuning hub, automatically retuning all compatible plugins in your session to a single scale, making the process seamless.
Another challenge is the “out of tune” perception. To a listener accustomed to Western pop, microtonal electronic music might initially sound “wrong.” The key is to use microtonality intentionally. Use consonance to ground the listener before venturing into more dissonant, microtonal territory. This creates a narrative arc that feels purposeful rather than accidental.
Conclusion: Start Your Microtonal Journey
Microtonal electronic music is an invitation to explore the full spectrum of sound. It breaks the invisible walls of conventional music theory and opens up a world of creative possibilities. By experimenting with different tuning systems and utilizing modern software tools, you can develop a voice that is truly your own. Whether you are aiming for mathematical purity or avant-garde exploration, the world of microtones is waiting for you. Start by downloading some Scala files and applying them to your favorite synth today to hear your music in a whole new light.
