The call and response thing is huge in Highland piping, particularly in 2/4 marches, due to the way the phrases are constructed.
I always think of this scene when the subject of the “when” to do something comes up!

Silly, but profound, and as true in comedy as it is in conversation, music, love, and many other things.
Those Eb’s that Sharnnon is playing in the 3rd part are really nice, and you really don’t hear it played that way too often - especially not on a flute.
Back on topic, I probably don’t have too much to add. I’m ‘self taught’ as most might put it. I had had some lessons as a child, but abandoned it, and I was already a working musician when I took up the flute and whistle seriously, and so just listened to everything I possibly could, played as much as I could, and played with as many different people as I could.
