Hi! Thank you for your interest in the images. I found the patterns with a Java program that I made. They are solutions to an equation called the Helmholtz equation, whose solutions are standing waves. The program finds those specific to a hexagon. I specify a frequency and the program computes the pattern along with some error measure. If error is very low, we're close to a resonant frequency. The resonant patterns should apply to most types of vibrations to some degree. The images don't display the frequencies directly, because those depend on type of vibration. For vibrating plates, the freq is ν² times a constant. Whenever there's at least 2 patterns at the same frequency, their combinations can produce a continuous range of possible patterns for that frequency. Maybe at some point I could make animated versions where one can see all the combined patterns as well. The images consist of all the first couple "normal modes", i.e. the building block patterns necessary to produce all other patterns

My name Rinaldi from Indonesia
I can not speak English , I am writing this email with the help of google translate
I am very interested in cymatic , but I do not know how it works ,
I am happy meditation with music that I like , just so curious as to what shape the image of the music that I heard when meditation
What you could help me ? ...
if you want , then will I send the music

Hello Jodina, thank you for your support!

The pool will be 3 meter diameter, and o course I will prefer not doing any hole in it.

If it´s possible to trasmit the vibration from outside it will be perfect!

The is gonna be in PVC 75/100 and it will be 50 cm high, that means that there will be around 3000 liter of water.

I could create a support in the bottom to support any vibration generator but I don´t know if this is enough and which kind of woofer I should use and how many.

Here you can find a short desctription of the project (the Cymatic part is not in there yet!)

Thank you very much

Thank you to reassure me!

the pool will be 3 meter of diameter. I don´t want to make a hole in the pool at all!!

I don´t understand how to transmit the sound, with which kind of technical equipment i need to have to transmit the vibration to the pool from outside.

Hello Jodina, thank you for accepting me in in this inspiring group.

I´m working on a cymatic project, it´s an artistic instalaltion taht will take place in milan (Italy) in April. I would like to fill a pvc pool with water and move it with sound frequecny vibration.

The only problem is that I still don´t know how to generate the frequency without making a hole in the pool, and I´m worry that the pvc material is too tick to transmit the sound waves to the water.

Jodie, I just signed up. Comment back to me regarding the instrument you were going to mail to me (when I get it, I can post some results!)

Hi Jodina,

Your Big Party pictures are great! Good stuff for kids!

This is awesome!

Thanks Jodi, I'll get started this weekend!

I can't wait to see what my daughters beautiful voice LOOKS like :-)

Another question: if I wanted to start experimenting with Cymatics at home, what materials should I pick up?

Is there any way to start experimenting with cymatics for less than $20 bucks?

Also, is this the kind of thing that's a good kids (0-3) activity, or in your experience is it a older persons thing?

Whoa - I don't have a helpful question for your course, but that last comment about a table in a bar gave me an idea.... What if you hooked a large loundspeaker up under the cymatics table, and had a slow cascade of sand / salt from above that kept filling it up... then you could point a camera at it and project the image of the table on a wall - the sound could be manipulated by a DJ... that would make for a crazy addition to a party or concert!

And depending on the kind of musinc the DJ was spinning, it could work really well with cymatics - I know a lot of electronic music is full of loud, droning tones that modulate slowly over time...

anyway, just a thought.

I was wondering if it could be used as some kind of table in a bar!!! It would look good. I don't know if it would work for 'normal' music as it seems to need a constant tone to create a nice design.

hmmm... that pic doesn't look like you....
