In his book "Hindustani Gata's Compilation - Instrumental Themes in Indian Classical Music", published early in 2012, French musicologist and sitarist Patrick Moutal presents an impressive compilation of gats which he has collected during his studying years in Varanasi between 1970 and 1983. Among them are, of course, not only the 70 to 80 well-known ragas, but also many lesser-known rare ones.

Most gats come from Lal Mani Misra and K. C. Gangrade, Patrick Moutal's teachers in Varanasi, and represent musical traditions, which are relatively little known outside India. But there are also gats from internationally renowned masters like Allauddin Khan, Nikhil Banerjee, Ravi Shankar, Vilayat Khan, Rais Khan, Imrat Khan, Balaram Pathak and Buddhaditya Mukherjee. V. N. Bhatkhande has also contributed, as well as several well-known singers from the first half of the 20th century. And last but not least Patrick Moutal has also included some of his own compositions. The gats were collected either from personal lessons, from written publications, or from transcriptions of published recordings.

All gats are notated in V. N. Bhatkhande's Svaralipi system, a letter notation using the characters of the Indian Devanagari alphabet which is explained in the book in full detail.
