🎵 Microtonality: Unlocking the Realm of New Musical Intonations
Have you ever wondered about the fascinating world of microtonality? In this article, we will delve into the specific terminology and concepts associated with microtonal music. While not an exhaustive guide, we aim to provide you with an overview using language that is accessible and relatable. So, let's embark on this melodic journey together and discover the wonders of microtonality!
1. Introduction
Music, as a universal language, transcends cultural boundaries and serves as a medium of expression. In western music cultures, we are accustomed to the 12-note system, known as the 12-tone equal temperament (12-TET). However, there exists a vast sonic landscape beyond these familiar intervals, waiting to be explored. Enter microtonality, the realm of musical intonations that lie between the cracks of conventional Western music theory.
2. Microtonality
🎶 Zen Harmonic Polychromatic: Unlocking New Musical Colors
Microtonality expands our tonal palette, offering a spectrum of pitches and harmonies that venture beyond the standard 12 notes. It allows composers to paint intricate soundscapes, incorporating quarter tones, fifth tones, and other microintonations. Zen harmonic polychromatic refers to the diverse world of sounds that exist outside the confines of 12-TET.
🎵 Unveiling the Secret: The Overtone Series
One of the fundamental concepts in microtonality is the overtone series. Each note produces an infinite series of harmonics, which are multiples of its fundamental frequency. This series forms the basis of an instrument's timbre and lays the foundation for harmony. The first five notes of the harmonic series form a major triad, a familiar sound to Western ears. The intervals in the overtone series can be expressed as whole number ratios, with lower ratios sounding more consonant.
🎵 The Unexplored Depths: Undertone Series
On the flip side, we encounter the undertone series, an inversion of the overtone series. While not as commonly employed, the undertone series offers a unique tonal perspective and can be explored for its distinctive qualities in microtonal compositions.
3. Tuning Systems and Notations
🎵 Embracing Equal Divisions: EDO and TET
To facilitate transpositions and explore different key signatures, various tuning systems have been devised. Among them, Equal Division of the Octave (EDO) and Tone Equal Temperament (TET) play significant roles in microtonal music theory. These systems divide the octave into equal parts, providing a framework for the expression of microtonal intervals.
🎵 The Pervasive 12-TET System
The most prevalent tuning system in the Western world is 12-TET. This system, popularized worldwide but historically developed in China, has become so ingrained in our musical culture that its imperfections often go unnoticed. However, once you experience the harmonic series and its nuanced intervals, the limitations of 12-TET may become apparent.
🎵 Exploring Beyond: 24-TET and 31-TET
In the pursuit of improved intonation and expanded tonal possibilities, composers and musicians have explored alternative tuning systems. One such system is 24-TET, which provides approximate quarter-tone intervals. However, even with 24 divisions, many overtones remain approximations. Enter 31-TET, a tuning system that strikes a delicate balance between the harmonic series and chromaticism, offering improved intonation and even introducing new intervals.
🎵 Unveiling the Past: Quartacoma Meantone
In the annals of musical history, various tuning systems have emerged, each with its unique characteristics. One such system is quartacoma meantone, which gained popularity during the 16th and 17th centuries in Europe. Its focus on achieving improved thirds resulted in the lowering of fifths by a quarter of a syntonic comma.
4. Intervals and Deviations
🎵 Quantifying Tonality: Cents
When discussing microtonality, we often encounter the term "cents." A cent is a unit of measurement used to describe pitch deviations from the 12-TET system. A semitone in 12-TET is divided into 100 cents. The average listener can distinguish pitch differences of up to approximately 5 cents.
🎵 The Semitone Saga
Typically, the semitone in Western music is 100 cents in size. However, different tuning systems may employ semitones ranging from around 80 to 120 cents. Additionally, quarter tones, with a size of 50 cents, have found their place in non-Western scales and melodies, despite their departure from equal temperament.
🎵 Embracing the Unique: Fifth Tones
In the pursuit of finer intervals, the concept of fifth tones comes into play. By dividing a whole tone into five equal parts, we can express distinctions that were previously imperceptible. This division allows for fine-tuning and distinguishes formally and harmonically equivalent notes as distinct pitches.
🎵 The Pythagorean Ripple: Pythagorean Comma
The Pythagorean comma is an intriguing phenomenon that occurs when stacking pure fifths atop one another. After 12 iterations, a tiny discrepancy between the starting and ending nodes is noticeable. This difference, approximately 23.46 cents, is known as the Pythagorean comma. The 12-TET system addresses this by dividing the comma into 12 pieces, ensuring a more cohesive circle of fifths.
🎵 The Syntonic Shortfall: Syntonic Comma
Similar to the Pythagorean comma, the syntonic comma arises from the difference between stacking four pure fifths and a pure major third. Its value is around 21.5 cents. The existence of these subtle discrepancies paves the way for alternative tuning systems that account for improved harmonic relationships.
5. Notating Microtones
🎵 The Language of Microtones: Shad and Flop
To notate microtones effectively, specific accidentals are employed. In our exploration, we utilize the terms "shad" to signify a slight raise in pitch and "flop" to represent a slight lowering of pitch. These monosyllabic words capture the essence of microtonal deviations and are versatile notations used in 24-TET and 31-TET.
🎵 The Nuances Unveiled: Fries and Heart
In addition to "shad" and "flop," we introduce two additional accidentals: "fries" and "heart." "Fries" represents a sharper direction, while "heart" signifies a flatter direction. These notations are employed in 24-TET and 31-TET to move a note up or down by three-quarters or five-fifths of a tone, respectively. These simple yet expressive symbols allow for precise communication of microtonal shifts.
6. Conclusion
In this article, we have scratched the surface of the fascinating world of microtonality. From understanding the overtone and undertone series to exploring tuning systems and notations, we hope to have provided you with a glimpse into the expansive universe of microtonal music. By embracing microtonality, composers and musicians can create captivating and unique sonic experiences that transcend the limitations of 12-TET. So, go forth, explore, and let your musical journey be enriched by the beauty of microtonality!
