Some say it is similar to Carnatic Kapi .
https://www.youtube.com/watch?v=ULhCbTOXhx8 - Pt Ajoy C - " kate Na Birha Ki Raat "
Includes Pt´s explanation about different types of harmonium accompaniment . ( complementary - filling , chordal , harmonium playing 2nd voice in thirds ...)
There is the bonus of him doing sargams , which seems to be rare in thumris ( ? ) .
Some murchana : Sa from komal ga , maybe also from shuddha Ga . ( in any case I heard it in this or another thumri by him )
