Many different Punjabi instruments contribute to the unique sound of Bhangra music. Although the most prominent is the Dhol Drum, a variety of string instruments and other drums play key roles in creating the sounds, rhythms and feel.
The 'Dhol' drum is widely used in India, usually in the Punjab region. It is said to have been invented by the Persian/Afghanis when they migrated to North India. It was incorporated into Gujrati, Punjabi, Rajasthani and other Indian cultures. The Dhol is very popular in modern Punjabi music.
The 'Dholak' is a classical North Indian hand drum. A Dholak may have traditional lacing or 'tumbuckle' tuning and is the main accompanying instrument of the Qawwali. The Dholak is often featured in Indian film music.
The Harmonium remains an important instrument in many genres of Indian music. A popular usage is by followers of the Sikh faith, who use it in the devotional signing of prayers, called 'Kirtan'. The harmonium is also commonly accompanied by the Tabla.
