Check out the piping forums at www.bobdunsire.com a forum dedicated to piping. Also google Andrew Lentz and his "Bagpipe Journey".

Piping is one of those things that can be easy or hard, depending entirely on the student. Some have trouble with the fingering, especially on embellishments. Other have a VERY hard time grasping the fact that pipe music is seldom played exactly as written, often there is an accepted "deviation" from the written page that results in more expression in the tune.

Anyone can learn to play, barring a physical handicap that would prevent one from blowing that hard. At what level they will play is dependant on the student, at what age they learned, their tutor and how much effort they put into it.
