I mentioned earlier that Bardic Circle is a beginner-friendly session. Here's a shining example: Larry Shicks, one of the guys from that session, showed up one day and told me he'd made me a whistle. So I bought him a pint, which seemed like a good way to say thank you. That's it on the right, and there's a close-up of the fipple at the end of this post. Click on the pictures to enlarge them.
The whistle is a low D made of PVC, with a wooden fipple. Note the offset finger holes and decorative paint. It's pretty quiet, requires a good bit of air, and has very little back pressure. The sound is reminiscent of a pipe organ or pan pipe.
I'm having a somewhat tough time getting a great tone out of it consistently. This is my first low whistle, so it could be just my own inexperience. The air requirements and back pressure are very different from my soprano whistles. Reaching the holes is no problem; standard grip works better for me than piper's grip, though. The only thing I have a hard time doing is keeping my bottom hand pinkie on the whistle.
