Trumpet Cymatics Researcher Wins Prize

by Jodina Meehan on February 15, 2013

We have a winner! As the 400th student to join the School of Cymatics, Tim Chrepta has won the video course, How To Make A Cymatic Voicebox!

He will be receiving the first copy fresh “off the press” as the course has just been completed and will be offered for sale next week.

Tim is a Graphic Design major in Philadelphia and has this to say about his work:

“[I am] currently doing an experimental thesis project based on the studies of cymatics using a trumpet. My plans are to hopefully film/photograph these patterns using water much like Alexander Lauterwasser’s studies and rebrand five jazz musicians based on the results.

“I’ve seen several videos exploring this type of idea using music but my problem is creating something that will produce high quality results and will respond to the sound of a trumpet. I am just not sure on how to go about in building this. I have a large speaker that I will be using for audio. Any advice?”

Do YOU have any tips or advice for Tim on his trumpet and cymatics project? Please leave a comment below!

If you are not yet a student at the School of Cymatics, you can check out Tim’s page here and join the first School of Cymatics while admission is still free.

Hi Tim,

Jodina referred me to you regarding this trumpet project, presumably because I play the trumpet.

First, this should make some interesting patterns becuase, as you know, the trumpet doesn’t just produce a sine wave. The sound from it is has a rich and complex overtone (harmonics) content.

My first thought is to simply mic the horn and use a speaker (piezo or conventional) in the usual manner that cymatic patterns are produced.

Alternately, one could use a tube and membrane similar to the voice visualizing contructs that Jodina has mentioned on her site. The only difference is taht the trumpet will have air coming out of it and it needs to go somewhere so the device should have some sort of vent but small enough tocreate backpressure so that the membrane is activated instead of all the sound going out the hole.

One could start with a mute as it would be tightly fitting into the bell and would allow you to direct all the sound where you want it.

To keep the costs down, I recommend checking out the “Renizit” musts on youtube made out of the air fresheners that you can buy in the supermarket for a dollar. Perhaps from there you can go with pvc tubing with a tee, with the straight though being narrow and restricting while the top “tee” part could be really wide diameter with a membrane like a stretched out balloon.

Hope this gives you some ideas, please keep me posted, this sounds like a great project.
