Arab Tone System
The modern Arab tone system, or system of musical tuning, is based upon the theoretical division of the octave into twenty-four equal divisions or 24-tone equal temperament, the distance between each successive note being a quarter tone (50 cents). Each tone has its own name not repeated in different octaves, unlike systems featuring octave equivalency. The lowest tone is named ''yakah'' and is determined by the lowest pitch in the range of the singer. The next higher octave is ''nawa'' and the second ''tuti''. However, from these twenty-four tones, seven are selected to produce a scale and thus the interval of a quarter tone is never used and the three-quarter tone or neutral second should be considered the characteristic interval. By contrast, in the European equally tempered scale the octave is divided into twelve equal divisions, or exactly half as many as the Arab system. Thus, when Arabic music is written in European musical notation, a slashed or reversed flat sign is ...
