Methods for Learning Tunes

[alistair]

As you may know there is a German maker of mouth organs who sells a model tuned to the bagpipe scale. I once phoned Scales to enquire about it and the guy I spoke to said, "Oh you mean the mixolydian model, sir". To which my only answer was "Do I?". Anyway I looked up the word in Wikipedia (which is how I found out how to spell it) and it was quite fascinating though it did not specifically mention the Highland or any other bagpipe. However I also found a US web site about tuning bagpipes (at http://www.hotpipes.com/tuning.html ) which uses the term extensively.
There is also a demonstration on UTube (at http://www.youtube.com/watch?v=rI-sOJfa744 ) of how to tune a guitar to a mixolydian mode.
