Sonido 13 is a theory of microtonal music created by the Mexican composer Julian Carrillo around 1900 and described by Nicolas Slonimsky as, "the field of sounds smaller than the twelve semitones of the tempered scale". Developed in 1895 while he was experimenting with his violin. As Carrillo was placing his finger over a violin string, he noticed that he could produce different sounds than the ones defined by musical convention. This way, he realized that the string could be divided into an infinite number of pitches, creating many more possibilities for music composition. Though he became internationally recognized for his system of notation, it was never widely applied. His first composition in demonstration of his theories was Preludio a Colon (1922).
