ViperPiper's Bagpipe Tunes

I believe this to be a rather old traditional tune. Leastwise, I hope so. I "composed" a third and fourth part to make it longer (I use quotes because the new parts really aren't all that different from the already existing first and second parts). Any input would be appreciated.

Bit of a mistake: the tune sounds better at 110 beats per minute. I believe that it is at some faster pace upon downloading.
