 How to place holes on a tube?

I am making a new home-made music instrument with a copper tube about 1 foot long, does anyone know how to arrange holes on the tube? I want to put the holes in the right place so I can get the correct tunes/pitches. The questions are, how many holes do I need to drill, how far apart are they?

You don't specifically state what instrument you are making, but here's some info.

The simplest instrument to make is a flute or whistle. The tin whistle is a typical example. It has six holes in a row. The first hole should be half way along the tube. THe other holes should be fairly evenly spaced along the rest of the tube. Play the lowest note of the instrument with no holes at all. Call this do. Drill the hole furthest from the mouthpiece end first and enlarge it until it sounds a "re". Now drill the next hole and enlarge it so that the instrument plays a "mi" when no holes are covered. Continue in this way. You should eventully be able to play it like a tin whistle, with the fingering given here:

Tim,

There is much research to read on the physics of this topic. A man by the name of Glenn Engstrand is quite knowlegable and has also written a small applet called WINDS. It is a little rough around the edges, but will be exactly what you're looking for.

Good luck on your new instrument. I'd look at recorders, a del rio sax, the tin whistle, etc for ideas. Basically any instrument without keys, that you play by covering holes.
