The art of Indian music is remarkable for its vocal culture, and it requires years of study to attain proficiency in it. Our instrumental music is considered next to the vocal in importance. The vina is the oldest instrument in the world's history, and it is also the only instrument for the correct production of Indian music. Indian dancing follows on the same principles as vocal and instrumental music. The Indian musician is recognized chiefly for the inspirational beauty he expresses by his improvisation. Therefore our composers are much less known, because their compositions are performed by each artist differently; only the foundation and poetry remain the same. The artist is supposed to be a composer himself before he can become an artist. Even if he sings one song it will be different each time. Therefore notation did not become universal in India until of late, when Moula Baksh, the great composer, invented a system of notation for beginners and founded a school on modern principles in the state of Maharajah Baekwar of Baroda.
