As J.S.Sanders already said, self taught is not a good idea if you want to get into piping seriously. When I was younger I went down the self taught route and could play about ten or a dozen penny whistle tunes on the pipes and one or two proper pipe tunes but with most of the grace notes omitted. There was no sense of timing and it was OK for solo playing to the tourtists from a static pitch. Later I considered taking up the pipes more seriously and went along to a tutor who said that if I ever wanted to play in a marching band I would need to forget all I knew and start again from scratch. I stopped playing for a few years then sold my pipes. Eventually I bought a new practice chanter and may yet start learning to play the pipes properly, but at the moment the local beginner's class in piping clashes with my Scottish Country Dance class.
