New reeds 'squealing'
I've been piping for a few years but this is a new problem that's popped up and has me a bit perplexed. Basically, I've been trying a few different new reeds (some medium, eg MacLellan and Shepherd) and one 'easy' (G1 Platinum).
I can get them all sounding fine and play with them for a good ten or 15 minutes before the same issue arises - some squealing, as if the air pressure's causing a problem, especially noticeable going from high to low notes. Any ideas what's causing this? It's not my fingering (been playing Killiekrankie, the classic high A to low A test, for years) and I can't see the reeds, esp the Shepherd, being too easy as I'm not that strong a blower.
On one occasion wetting the reed seemed to help, as did toughening up my drones so they took more air, but I can't seem to get them staying stable for more than quarter of an hour.
Hope you can help!
