Introduction to Microtonality
The idea of microtones is not new. They have been part of musical traditions for centuries. Microtones are musical intervals smaller than the traditional semitone, the smallest interval in Western music.
The twelve-tone equal temperament (12-TET) system is common in Western music. It divides the octave into twelve equal parts. But microtonal music uses intervals smaller than a semitone. This allows for a more detailed division of the octave.
Definition of Microtones and Microtonality
Microtones are intervals smaller than a semitone. Microtonality is the use of these microtonal intervals in music. It allows for a wider range of pitch variations and expanded pitch range.
Importance of Microtones in Music
Exploring microtones can add new dimensions to music. It allows for subtle changes in pitch that can evoke different emotions and musical texture.
Microtones are used in various non-Western music traditions around the world. For example, Indian classical music uses 22 śrutis (microtonal intervals). Middle Eastern music uses quarter tones. By going beyond the twelve-tone equal temperament, microtonal music can create pitches not accessible on standard instruments. This unlocks a wider range of expressive possibilities.
| Music Tradition | Microtonal Intervals |
|---|---|
| Indian Classical Music | 22 śrutis (microtonal intervals) |
| Middle Eastern Music | Quarter tones (150 cents), half tones (100 cents), and whole tones (200 cents) |
| Western Composers | Quarter tone (50 cents), 6th tone (33.3 cents), 12th tone (16.7 cents), and 16th tone (12.5 cents) |
Standard Tuning vs. Just Intonation
In music, picking between 12-tone equal temperament (12 EDO) and just intonation (JI) changes how your music sounds. 12 EDO has been common in Western music for a long time. But JI offers a different way that’s worth looking into.
12 EDO splits the octave into 12 equal parts, making key changes smooth. JI, on the other hand, tunes notes to precise ratios from the harmonic series. This makes intervals sound “pure” without any beating.
JI’s intervals, like the major third and perfect fifth, match the natural sound of music better. This makes your music sound more natural and harmonious. It’s great for those who want a more organic sound.
But, 12 EDO is more flexible, even if its intervals aren’t as “pure”. This flexibility is why 12 EDO is so popular in Western music. It makes changing keys and modulating easier without needing to retune instruments.
| Characteristic | 12-Tone Equal Temperament (12 EDO) | Just Intonation (JI) |
|---|---|---|
| Interval Tuning | 12 equally spaced pitches per octave | Precise integer multiples based on the harmonic series |
| Interval Purity | Slightly compromised for the sake of flexibility | Pure, harmonious intervals without beating |
| Key Changes and Modulations | Seamless and easy to execute | Can be more challenging, as instruments may need to be retuned |
Choosing between 12 EDO and JI depends on your musical goals. Both have their good points and bad points. Knowing the differences can help you explore new sounds in your music.
Half Steps and Cents
In music, microtonal pitches are more than the 12-note chromatic scale. They are notes above or below the 12 EDO scale by a certain amount. This amount is often shown as a percentage of a half step or in cents.
For example, there are 100 cents between two keys on a piano, like C and C#. The pitch C +50 cents is a quarter-tone or half the distance to C#. It can be notated as a quarter-tone sharp.
Understanding Microtonal Intervals
Music with quarter-tone variations uses special accidentals. These include quarter-tone flat, three-quarter tones flat, quarter-tone sharp, and three-quarter tones sharp. Microtonal tunings can alter tones by any number of cents. This creates a wide range of pitch bending options.
Notating Microtones
Notating microtonal pitches is a big challenge for microtonalists. Traditional Western notation struggles to accurately show microtonal pitches and enharmonic microtones. Some composers have created their own alternative notation systems.
Yet, in many cases, the sounds of Eastern instruments or experimental tunings are learned over generations. Musicians understand these sounds through practice and familiarity, not just through notation.
| Interval | Cents |
|---|---|
| Major Third | 400 |
| Perfect Fifth | 700 |
| Minor Seventh | 1000 |
| Octave | 1200 |
The table shows the number of cents in common intervals. It highlights the need for precision in representing microtonal pitches and their deviations from standard tuning.
Microtonality Terminology
Exploring microtonality means knowing some key terms. Meantone temperament can be a specific tuning or a group of them. These tunings use perfect fifths and slightly flatten intervals to match major thirds better.
The comma is a small interval, about an eighth-tone (0.25 semitone or 25 cents). It shows up in just intonation or when looking at musical intervals as ratios.
Limit
The limit shows how complex a tuning system’s ratios are. An n-limit includes all ratios of odd numbers up to n. For example, a 5-limit system is known as classic just intonation.
Knowing these terms helps you explore microtonal music. It ranges from old temperaments to new microtonal intervals and pitch systems. Whether you make music, play it, or just love it, learning about microtonality can reveal new musical possibilities.
Other Divisions of the Octave
Exploring microtonal music opens up a world of alternate tuning systems. These systems go beyond the 12-EDO used in Western music. They introduce new harmonic possibilities, allowing for deeper exploration of the harmonic series and other principles.
EDOs like 5-EDO, 7-EDO, 19-EDO, 22-EDO, 24-EDO, 27-EDO, and 31-EDO offer unique sounds. They expand the musical palette, creating ethereal and otherworldly timbres. These tunings can transform your music into something truly unique.
| EDO | Intervals | Musical Applications |
|---|---|---|
| 5-EDO | 286 cents | Indonesian gamelan music, microtonal folk traditions |
| 7-EDO | 257 cents | North African and Middle Eastern music, avant-garde composition |
| 19-EDO | 63 cents | Contemporary classical, experimental electronic music |
| 22-EDO | 55 cents | Arabic and Persian music, microtonal exploration |
| 24-EDO | 50 cents | Avant-garde and electronic music, quarter-tone composition |
| 27-EDO | 44 cents | Microtonal research, experimental music |
| 31-EDO | 38 cents | Contemporary classical, microtonal exploration |
These alternate tuning systems offer endless creative possibilities. They allow musicians and composers to explore beyond traditional Western music. By embracing these unique tunings, you can discover a new world of sound and artistic expression.
