(see D below)
We heard Alistair Fraser and Natalie Haas playing this together, but took it down a fifth to make it easier to play.
Thankfully, we don’t play it as fast as Alistair and Natalie… perhaps more the speed that Kierah plays it (although we don’t tend to call it cal-li-pi house) and I found this nice recording of a guitar and fiddle together and again, different players and slower. Don’t forget, however, that most of these recordings are playing Calliope House in D (a fifth higher), so you can’t play along with them, except this one of Noah and Alex in a pub, way back in 2012 when they were only ten years old.
Since it is often played in D, I’ve now (2022) added the music for Calliope in D (see below). It is not hard for fiddlers to switch between keys as the same fingering goes up a string, but it might be useful for other instruments.

And if you would like it an octave higher or in another clef…. I hope this helps. (and pdf here).

Where the tune comes from:

The history about the tune is explained here: http://slowplayers.org/2014/05/04/calliope-house/
So we’ve taken it down yet another 5th from D, where it had already been transposed. We also generally play the high part as the B part.
Very helpful,thanks,to have the chords. I am a whistle player in Cornwall but currently Zooming,glad to join any remote sessions you are doing.
