Cutting and Tuning Robotic Glockenspiel Chimes

After a few weeks of experimentation, I think I can now write sensible notes on how to cut and tune the chimes for a glockenspiel (metal xylophone) out of metal conduit. This is the first step of my Robotic Glockenspiel project, which I hope to end with a network-connected, Arduino-controlled set of chimes that can play Christmas carols.

The Co-Presidents in Britain

In the fall of 2000, the co-presidents spent a month in Wales and England. For Linda it was a research trip into English king Edward’s medieval castles (built to crush the Welsh), and into various Victorian museums covering everything from candy to coal.

Stage One is a fundraising organization for the Hillsboro area high schools’ performing arts departments.

What Exactly is Singing “In Tune”?

I’ve sung most of my life, yet only recently have I started to ask the question “How do unaccompanied vocalists stay in tune?” The process sounds simple enough at first: vocalists stay in tune because they have good relative or absolute pitch memory — they remember what the 5th of the scale sounds like, and can sing it whenever they like. This explanation works at some level, but a few nagging questions remain.
