Indian classical music is bound by the melodic system of ragas and rhythmic system of talas. A raga is a specific melodic unit based on one of many Indian scales and determined by the notes used, their ascending and descending sequences, hierarchy of importance, association with a time of the day or night and emotions. E. Kubièková is presenting ragas of the North Indian branche of Indian classical music. The performance of a raga consists of the slow opening part called the alap, played by the soloist, which is followed by composed and improvised parts of the gat, organized to fit into a particular tala, played by a tabla player. The musicians play usually two gats in various tempi, they must understand both raga and tala thoroughly and obey their constraints to create the improvisations.
