Project Information
Yes this is a wood project, just look at those dovetails in the base! I made this for a child's Christmas present. It is a full C scale octave plus a high D. Of course you could add more tubes at either end to lengthen the scale, or even add the sharps and flats to make a more versatile instrument for adults.
I only had to buy the copper tubing, which is about $10 for a 10 foot section.
All you need is
Copper tubes must be tuned to the correct frequency, and there is a lot of variation in the tubes. So cut your first tube maybe a 1/4 inch larger than the table shows below. Measure in 22% from each end and temporarily suspend the tube from these points, using two strings with a loop on the end of each. Hit the tube in the middle with a piece of wood or dowel and measure the frequency using the music tuner. Now trim it down with a file and measure again. Repeat until you have the correct note.
After all the tubes are cut and tuned, drill a hole at each end of each tube at the 22% point. Use a marker to mark the note on each tube.
Wood base total length is 13 3/4", one side 8", the other side is 6", all three boards 3" wide.
I made the mallets using some old tent poles for the handle, although you could use some dowel. I used a larger piece of dowel for the end, wrapped with a piece of cloth. The cloth makes the lower tones sound better.
I used string initially to hang the tubes, but I believe the child stood on it and the string broke. For the second attempt I used picture hanging wire. See the last photo.
C scale octave plus high D:
note/frequency (hz)/length (inches)
C 1046.5, 10 1/8 in
D 1174.7, 9 1/2
E 1318.5, 8 15/16
F 1396.9, 8 11/16
G 1568.0, 8 3/16
A 1760.0, 7 11/16
B 1975.5, 7 1/4
C 2093.0, 7
D 2349.3, 6 5/8
Here are some music sheets for simple and easy songs for the xylophone. The high C and high D are marked with a 2 suffix:

I only had to buy the copper tubing, which is about $10 for a 10 foot section.
All you need is
- 6 1/2 feet of 1/2 inch copper tubing; you can also use 1/2 inch electrical conduit but the lengths will be different
- music tuner (buy one or borrow one from your nearest garage band) or use a phone app
- 1/2 inch thick wood for a base
- string or wire to mount the tubes
- plastic straw for separators - I tried wood dowels and paper straws and both mute the strings
