Chaturang – Indian classical music form
It is a very appealing style of singing that compactly combines sections from four diverse classical forms – khayal, tarana, sargam and tirwat, all in the same raga. A crisp bandish with a well-structured sthayi and antara is rendered at first in madhya or drut laya. This is followed by a rapid tarana, which in turn gives way to sargam and the performance is rounded off with an enchanting tirwat, or the melodic use of pakhawaj and tabla bols. Like khayalnuma and tarana, chaturang relies, for the better part on the use of meaningless sounds to develop ragas. Yet, as the word chaturang signifies etymologically, it brings together a spectrum of four (chatur) ‘colours’ (rang) into one band. Each stands separately, but the whole coalesces to give a ‘rainbow’ effect.
चतुरंग-ख्याल या गीत,तराने के बोल,सरगम तथा मृदंग की परन इन चारों से रचा हुआ गीत चतुरंग कहलाता है।
