This is a clip of the Jubilee Bi-Whistle. It’s a double-barreled brass whistle with a single mouthpiece. The tune is my own variation on a traditional American psalm or hymn tune.
It’s at Clips & Snips: http://www.tinwhistletunes.com/clipssnip/Audio/11-05/variationlWalden.mp3
Neat! Lovely tune, sounds almost like a Medieval dance.
That whistle sounds fantastic–I’d always wondered what a whistle would sound like with a drone.
Very very cool! And well played–thanks for posting this!

Nicely played Walden! Great clip!
Sounds great. 
My ear is so bad–is that the regular BiWhistle or the Drone BiWhistle? If the former, how are you approaching the tune?
It’s the latter. I tongued it to give it that particular sound. You can get more of a bagpipe-type drone, by not tonguing.
