Indian classical music is broadly divided into two major streams known as Hindustani classical music and Carnatic classical music, each with its own historical evolution, stylistic features, performance practices, and cultural contexts, yet both sharing a common foundation rooted in ancient Indian musical traditions such as the concepts of raga and tala.

Hindustani classical music is primarily practiced in the northern, western, and central parts of India. Its development was significantly influenced by historical interactions with Persian and Central Asian cultures during the medieval period, particularly under the patronage of the Mughal courts. This cultural synthesis led to the evolution of a style that emphasizes improvisation, emotional expression, and the gradual unfolding of a raga. The structure of Hindustani music performances typically begins with an alap, a slow and improvisational introduction that explores the raga without rhythmic accompaniment, followed by compositions set to specific talas, such as vilambit (slow tempo) and drut (fast tempo) sections.

Each raga is associated with particular moods, times of day, and seasons, and the performer’s creativity plays a crucial role in bringing out its essence. The tala system, which governs rhythm, is equally important and includes cycles such as teentaal, jhaptaal, and ektal.

Thumri, on the other hand, is more lyrical and expressive, often focusing
