Here's another tune, the Christmas carol Adeste Fideles or O Come All Ye Faithful.

It's cool when a nice descant/countermelody line can be found that works as a harmony. In this case the low hand is playing D C# B A B C# D while the upper hand is playing the melody at the start of the second phrase.

I'm going to try to get Gibson to make me a pair of cocobolo A smallpipe chanters with certain holes missing so that this thing will play in a more normal key and also look more like a Renaissance pipe.

There are numerous carvings around Britain showing that bagpipes with two chanters were quite common at one time. For some reason they died out leaving only single chanter pipes.
