Just harmonium! Took a class online during a time I wanted to be a kirtan wallah. Yes I did get into play kirtan, but never had an audience. Was just doing it for my own practice. I don’t play kirtan much any more, I’ve shifted it into hymn singing in the Christian tradition which resonates with me more. But I remember the 10 thaats exercise and how fun it was to fly up and down the keyboard singing “sa re ga ma pa da ni sa” in different scales.
Oh I can image how difficult it would be to do with the voice. I have a problem skipping whole steps when I sing much less half steps which you would have to do frequently haha.
Shanti Shivani is the woman that I briefly studied Nada Yoga with a few years ago. She was a wandering hippie Sadhu in India for a time back in the 60’s and 70’s (very unusual for a Western woman!). After a period of seeking with a number of teachers and practices she discovered Nada Yoga and Dhrupad singing as her path. It was interesting to study briefly, but it’s a demanding path that I didn’t really have the time to pursue. She lives in Oregon.
