Esraj is a traditional Indian string instrument. It has 19 strings consisting of 4 main strings. The rest is formed into two octaves of resonant strings tuned into given gamut.

Tabla is a set of two drums. The drum on the right side is called dayan and is tuned in the key tonic. The left-side drum is called bayan and is tuned into bass.

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. Kubidkova is presenting Ragas of the Norht 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 imrovised parts of the Gat, organised to fit into a particular Tal, 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.
