As the trio, accompanied by a researcher, traversed the state's four cultural zones, from the Puad region to the Doaba, from the Majha region to Malwa, the canvas came alive with classical, folk, bhakti, tribal and modern expositions. The classical tradition boasts the Sham Chourasi Gharana whose chief proponents shifted to Pakistan after the Partition and the Patiala gharana of which the best known is the unparalleled Ustad Bade Ghulam Ali Khan and, more recently, Parveen Sultana. The study also throws light on the pardtaal, an amalgamation of the Dhrupad and Khayal styles, typical of only Gurmatt Sangeet, unique to all music forms in the world.
