If you play with someone who plays an instrument like that you do. I spent several years playing tunes with a Northumbrian Small Pipes player. There were quite a few tunes he could not play. The instrument is virtually locked into playing F# as G although that is not related to modes.

The modal nature of the music pipes produce is not something I would label as an idea. There is no thought required. That is just what they are able to play.
