Fingering techniques and how they are taught depends largely on the personal preferences of musicians rather than on the basis of school affiliation. Radhika Mohan Maitra, for example, used the index, middle and ring finger of his left hand to stop the string, just like followers of Allauddin Khan do. Maitra, however, made much more extensive use of the third fingernail for slides and hammers. Amjad Ali Khan, while a member of approximately the same stylistic school as Radhika Mohan, prefers to use just the index and middle fingers of his left hand. Amjad Ali is, however, pictured circa 1960 playing with all three fingers.
