Ok, at this point, I am teaching myself Bansuri (A Scale) by playing simple tunes 10-15 min a day (totally swamped nowadays)

Playing Om Jai Jagdish Hare it quite straightforward (plus I am familiar with the tune)

But how can I play Satyam Shivam Sundaram

I am very familiar with this melody, but how do I do the following, i.e.

Ishwar | satya | hai M~G G | g S | S~g

In other words, how do I transition between notes when there is ~

And how to treat notes that are between brackets () and curly braces {}

Please guide
