Collapse of Classical Music in Pakistan
There are several reasons for the collapse of Hundustani Classical music in Pakistan after partition, apart from official apathy. Before independence Lahore was a an important cultural center in North India. Affluent Hindu and Sikh families were the main patrons of music. Most of these patrons migrated to India after partition. Interestingly many muslim artists chose to migrate to Pakistan from India - Amanat Ali Khan, Barkat Ali Khan, Bade Ghulam Ali Khan and Fateh Ali Khan of the Patiala gharana; Ustad Salamat Ali Khan and Nazakat Ali Khan of the Shyam Chaurasi gharana; Roshanara Begum of the Kirana gharana; Asad Ali Khan (Ustad Fayyaz Khan's nephew) of the Agra gharana and Sardar Khan (Taanras Khan's grandson) of the Delhi gharana. But the patrons had migrated out of Pakistan. The artists realized that the old system of patronage had collapsed. Pakistan government (through Pakistan Radio), unlike All India Radio refused to step in as the chief patron. Wisely Bade Ghulam Ali Khan decided to migrate back to India after a few miserable months and had a very successful post independence career as well. Though in the beginning, official Pakistan govt. policy was very tolerant, later Increased criticism from orthodox quarters influenced the official policy which proceeded to discourage many forms of Hindustani music like Dhrupad, thumris and dadras as un-islamic. The artists were left at the mercy of the market and they had no market. They gradually lost their audience. They either dissuaded their children from following in their footsteps or the children themselves opted for film music or ghazal singing. In the last decade, some of them moved to pop music — about half of those singing or playing in the pop groups are children of the great masters. So Pakistan lost out on its musical heritage. But those who migrated to Pakistan and chose to sing mainly ghazals later gained prominence in, like Mehdi Hassan, Farida Khannum, Iqbal Bano and Mallika Pukhraj.
Found this very interesting! I always wondered why classical music did not flourish in Pakistan, while some of the most famous names in India were Muslim.
