Exploring Instruments Capable of Playing More Than 12 Notes

The world of music is vast and diverse, with a variety of instruments capable of producing microtones and quarter-tones beyond the standard 12-note chromatic scale. This article explores these unique instruments and musicians who push the boundaries of traditional music theory.

Understanding Microtones and Quarter-Tones

Microtones are intervals smaller than a semitone and can be found in various cultural and traditional music systems. Quarter-tones, in particular, are intervals that are a quarter of a semitone in size. The ability to play these microtones allows musicians to explore new sonic landscapes and express emotions more deeply than with the standard 12-tone scale.

Musicians Utilizing Microtones

The flugelhorn, a member of the cornet family, is one such instrument that can play quarter-tones. Yazz Ahmed, a notable musician, uses a specially-modified flugelhorn to produce these quarter-tones, adding a unique and compelling sound to her performances. Her work is featured in the article “Interview: Yazz Ahmed – Inspiring Expirations,” published in September 2018 by Rhythm Passport.

reed Instruments and Glissando

Many reed instruments, such as the clarinet, can produce glissandi, which are rapid sliding movements between notes. In the opening of Rhapsody in Blue, the big clarinet glissando is an excellent example of this technique. Additionally, saxophonists like Johnny Hodges often bent and glided between notes, creating a captivating sound. Clavichords, unlike harpsichords and pianos, support vibrato, further expanding the tonal palette.

Stringed and Keyboard Instruments

Stringed instruments, both fretted and fretless, like guitars and violins, can also play microtones. Musicians can achieve this by precise finger placement or by bending the strings. Modern keyboards often feature pitch wheels or shifters to allow for such microtonal manipulation. Older keyboards, such as the Mellotron, can also play more than 12 notes due to mechanical tuning issues.

The Human Voice and Drums

The human voice and whistle are inherently capable of producing microtones. Musicians can control pitch with minimal adjustments in their vocal cords. Drums can also be tuned to achieve specific tonalities, and the trombone and swan whistle, with their slide mechanisms, can move between pitches seamlessly.

Brass and Wind Instruments

While not all brass or wind instruments are designed to play more than 12 notes, some can accommodate this requirement. For instance, a skilled player like the author's stepson can produce unusual notes on the flute using his embouchure. These notes may not always be intentional, but they add depth and complexity to the music.

Exploring instruments capable of playing more than 12 notes opens up new avenues for musical expression and creativity. From the modified flugelhorn of Yazz Ahmed to the natural glissando of clarinets, musicians are constantly pushing the boundaries of traditional music theory. The result is a rich tapestry of sounds that reflect the infinite possibilities of human expression.
