Yeah, I'm aware that this is often the arrangement between teacher and student in India or Pakistan. My teacher was Nepali and studied both with his childhood teacher in Kathmandu and also with Suresh Talwalkar in New Delhi. We were actually about exactly the same age when I studied with him (both in our late twenties). So it was a much less formal arrangement because he was not exactly my elder. Also, it was an American setting as he was living around Denver, Colorado in the US.
Regardless, I still felt I owed him a great deal of respect because he took his music very seriously. He was legitimately a virtuoso at Tabla. Truly an amazing player. And I was committed to practicing diligently. Since life in the US didn't permit me to study all day with him, I spent a lot of time finding recordings of performances on Youtube to learn from. As I mentioned, my favorite performer other than my teacher was Anindo Chatterjee. My teacher also knew of Chatterjee and enjoyed his playing as much as I did. Since he was from a younger generation, I don't think he was bothered by my trying to learn from watching other players while I wasn't practicing with him.
Anyhow, nice to see mention of Tabla on Hacker News :).
