Buzzing tube length?

[bassbonebuster]

Is there an ideal length for using a vinyl tube to buzz with?

I think Ralph Sauer uses a 9 inch length for his F.A.R.T. I tried a 9 foot long tube to simulate a trombone. Both work. As does any size from about 4 inches to 20 feet. Or make a Hose-A-Phone.

Sauer also recommends drilling a hole in one side, about 3” in from one end.

I find that I like about 4-1/2 inches, with a hole punched as far in as I can get a standard hole punch.
