Quarter-Tone System

Quarter-Tone System

 

a tonal system based on the division of the octave into 24 equal intervals of a quarter tone instead of the usual 12 halftones. Theoretical work on the quarter-tone system began in 1910, and several composers have used the system in their works. The most prominent exponent of the quarter-tone system was the Czech composer A. Hába. In the USSR, A. M. Avraamov and G. M. Rimskii-Korsakov experimented with the quarter-tone system.

This radical option is exploited to the full: when Haba sets out the possibilities for the maximum construct exploitation of the different tone systems, he speaks of seven-tone chord in diatonics, twelve-tone chord in chromatics, twenty-four tone chord in the quarter-tone system and so on.
Moreover while the use of the quarter-tone system on the one hand secures the opera Matka a special place in world opera repertoire, on the other its specific requirements make it a piece for which few companies would have the resources.
