It is a challenge to play Bagpipes with other instruments. It is not impossible, but you have to spend time getting them set up for that. Bagpipes had a different or special tuning when compared to other instruments. We play in the key of Bb, but normally it is tuned higher than that. There are special chanters, the part the musical notes are played on, that will tune down to the Bb key.
The Marietta Piper has the necessary equipment to enable to play with other instruments. If you would like him to set up, please let him know in advance.
