Qawwali in the context of "Devotional song"

Delhi, officially the National Capital Territory (NCT) of Delhi, is a city and a union territory of India containing New Delhi, the capital of India. Straddling the Yamuna river, but spread chiefly to the west, or beyond its right bank, Delhi shares borders with the state of Uttar Pradesh in the east and with the state of Haryana in the remaining directions. Delhi became a union territory on 1 November 1956 and the NCT in 1995. The NCT covers an area of 1,484 square kilometres (573 sq mi). According to the 2011 census, Delhi's city proper population was over 11 million, while the NCT's population was about 16.8 million.

The topography of the medieval fort Purana Qila on the banks of the river Yamuna matches the literary description of the citadel Indraprastha in the Sanskrit epic Mahabharata; however, excavations in the area have revealed no signs of an ancient built environment.From the early 13th century until the mid-19th century, Delhi was the capital of two major empires, the Delhi Sultanate and the Mughal Empire, which covered large parts of South Asia. All three UNESCO World Heritage Sites in the city, the Qutub Minar, Humayun's Tomb, and the Red Fort, belong to this period. Delhi was the early centre of Sufism and Qawwali music. The names of Nizamuddin Auliya and Amir Khusrau are prominently associated with it. The Khariboli dialect of Delhi was part of a linguistic development that gave rise to the literature of Urdu and later Modern Standard Hindi. Major Urdu poets from Delhi include Mir Taqi Mir and Mirza Ghalib. Delhi was a notable centre of the Indian Rebellion of 1857. In 1911, New Delhi, a southern region within Delhi, became the capital of the British Indian Empire. During the Partition of India in 1947, Delhi was transformed from a Mughal city to a Punjabi one, losing two-thirds of its Muslim residents, in part due to the pressure brought to bear by arriving Hindu and Sikh refugees from western Punjab.After independence in 1947, New Delhi continued as the capital of the Dominion of India, and after 1950 of the Republic of India.

Headbanging is the act of violently shaking one's head in rhythm with music. It is common in rock, punk, heavy metal and dubstep, where headbanging is often used by musicians on stage. Headbanging is also common in traditional Islamic Sufi music traditions such as Qawwali in the Indian subcontinent and Iran.

A tabla is a pair of hand drums from the Indian subcontinent. Since the 18th century, it has been the principal percussion instrument in Hindustani classical music, where it may be played solo, as an accompaniment with other instruments and vocals, or as a part of larger ensembles. It is frequently played in popular and folk music performances in India, Bangladesh, Afghanistan, Pakistan, Nepal and Sri Lanka. The tabla is an essential instrument in the bhakti devotional traditions of Hinduism and Sikhism, such as during bhajan and kirtan singing. It is one of the main qawwali instruments used by Sufi musicians. The instrument is also featured in dance performances such as Kathak. Tabla is a rhythmic instrument.

The word tabla likely comes from tabl, the Arabic word for drum. The ultimate origin of the musical instrument is contested by scholars, though earliest evidence trace its evolution from indigenous musical instruments of the Indian subcontinent; drums like structure is mentioned in Vedic-era texts.
