Traditional Indian music is a reflection of the country's extreme cultural diversity. There is a very rich legacy of cultural music in India which has been developed over several eras and spans centuries. Most often, the traditional music genre primarily includes devotional music, ghazal, qawwali and patriotic songs among others. Since music can now be easily recorded, there has been seen a revival of the traditional style and its popularity remains intact. The several dozen ethnic groups in the state have contributed to a great variety and consequently we find a number of different types of traditional music which have developed over the centuries. The most well known forms and types of traditional music prevalent in India are mentioned below.
Qawwali: Qawwali is a vibrant musical tradition of India, which stretches back more than 700 years. It is a kind of devotional music performed mainly at Sufi shrines throughout what is now India and Pakistan, and has also gained mainstream popularity. The Qawwali songs are mostly heard in Urdu language and the Punjabi language, but they are also available in Persian, Brajbhasha and Siraiki. Qawwali can also be enjoyed in some regional languages but the sound of it is quite different from the conventional counterpart. The central themes of qawwali are love, devotion and longing (of man for the Divine). Songs in Qawwali are usually between 15 to 30 minutes long. It is performed with one or two lead singers, several chorus singers, harmonium, tabla, and dholak. The principles of Qawali music are based on Hindustani Classical music.Ghazal: A Ghazal is a poetic form consisting of couplets, which share a rhyme and a refrain. The word means 'the mortal cry of a Kastori doe'. A Ghazal, thus, is a collection of couplets (called sher), which follow the rules of Matla, Maqta, Beher, Qafiya, Radif, Khayaal and Wazan. The traditional complete ghazal has a matla, a maqta, and three other shers in between. The first two shers of a ghazal have the form of a qatha. Strictly speaking, it is not a musical form, but a poetic recitation. Today, however, it is commonly conceived of as an Urdu song, with prime importance given to the lyrics. In some modernized ghazals the poet's name is hidden somewhere in the last verse, usually between the front and end of a word. The ghazal is a common song form in India and Pakistan today.
Bhajan and Kirtan: A bhajan or kirtan is a Hindu devotional song, often of ancient origin. A lot of importance is attached to the singing of Bhajans with Bhakti, i.e., with loving devotion. Kirtans are deeply rooted in the tradition of the Veda. Bhajans are often simple songs in lyrical language expressing emotions of love for the Divine, either for a single God/Goddess, or any number of divinities. Many bhajans feature several names and aspects of the chosen deity, especially in the case of Hindu sahasranamas, which list a divinity's 1008 names. Traditionally, the music is based on Indian classical music, which is based on ragas and tala (rhythmic beat patterns) played on the Veena, Sarangi, Venu (flute), Mridanga (or Tabla) (traditional Indian instruments). The Scripture of the Sikhs contains 31 ragas and 17 talas, which form the basis for kirtan music compositions. Various traditions of bhajan-singing, such as Nirguni, Gorakhanathi, Vallabhapanthi, Ashtachhap and Madhura-bhakti, have been formed over the ages. Each sect has their own sets of bhajans and methods of singing. The traditional form of bhajan in South India is known as Sampradya Bhajans. In the past few decades, this has seen a great upsurge in popularity.
