I am considering a unit on waves and want to get my students to make wind
chimes and xylophones. I now realize that I don't know as much about it as
I used to think I did. How do I calculate the frequency of a wave in a
struck pipe, rod, or bar. Which plays the bigger role: the transverse or
the longitudinal wave in the pipe. How does the air in the pipe or around a
rod or bar affect the tuning. I have heard that humidity affects even the
tuning of a xylophone.

I saw a different kind of alarm clock in a catalog. It had what the
catalog called a "zen chime", a metal rod suspended by two strings
about a quarter the length from each end of the rod. It reminded me
of a similar device I saw in Hallmark. You tap it and it seems to
ring for about a minute. Very soothing.
Anyone know more about this: type of rod, exactly where to support
it, how to maximize the ringing time, etc.? Thanks, group.
