And now the fun part...
These tubes are:
• 74cm in length
• produce musical overtones in Key of A . Notes range from: Low A, E, Hi A, C#
• a frequency ratio of 3/2.
That's as much of the musical science as I can tell you.
As described by Paul Doherty Here's how it works:
Hold one end in your hand.
Twirl the other end in a circle.
Listen to the sound made by the tube.
Vary the speed of the tube.
Notice that the pitch of the whirly jumps from one note to another and increases as the speed of the twirling is increased.
That is, high speed twirling creates high pitch notes.

The Presentation I began by twirling the three foot long children's toy whirly over my head playing a series of notes up and down the scale. "I fell in love with the sounds of the whirly the first time I heard children playing them in the Exploratorium store. Whirlies only play notes which sound good together. No matter how I swing it around, it only plays certain notes. It does not slide from note to note it jumps. It thus behaves like the electron in an atom which jumps between energy levels. The whirly plays quantum music." After I had played the toy whirly for a while I got tired of the same five notes and began looking for other corrugated singing tubes. I conceived of a plan to incorporate the whirly into symphony orchestras. I envisioned a whole new orchestral section based on corrugated plastic tubes: the corrugahorn section. /* ssgST: excluded from sampling */ |
