I noticed a cool phenomena while doing dishes this evening.
I had filled a large glass bowl with water to soak away sourdough starter. It takes a while, the stuff is like glue.
Meanwhile I'm rinsing other plates before popping them in the dishwasher. One of them was caked so I figured I'd just
pop it into the already soaking bowl.
Well it sounded awesome!
As the smaller plate took on water it slowly worked it's way back and forth sometimes double tapping, sometimes single, but the resonant echo of the liquid coming from the miniature acoustic amphitheatre of the sink was quite mesmerizing as it descended down the musical scale.
Did it few times before getting back on task. Don't regret it one whit.
I propose an aquatic piano of sorts where not only does the position of the striker on the bowl produce a note, the strength at which the striker hits the glass changes the vibration of the ripples on the surface so as to change the resonance of each note as desired.
I've never heard anything like it. It was cool. Picture StarWars laser sounds but under water.

Was the tone percussive or did it contain some varying note as the inner bowl, the striker, dinged the 'bell' part? Cool. |
|
| |
Make a recording so we all can hear it. |
|
| |
There are several reasons why I am not going to record it, not the least of which is that my lapboard is an old piece of shit and will no longer sync with my phone... or I would have uploaded many more things over the last couple of years. I'm cheap, and will use this one til it dies. |
|
| |
But more than that... I've told you all that it sounds awesome and so you can take that to the bank. Do your own experiments with percussion from within a glass bell housing. |
|
| |
I notice things, I speak up, and then somebody else runs with it... |
|
| |
...That's just how it works. |
|

On a side note you'd be amazed at how many of my contributions had more than fifty votes before the crash of '04 when all votes were lost. |
|
| |
...or amazed at how many of my prior musings have become reality since that glitch. |

As the inventor of the Aeolian Pipe Dream (link) you will understand my interest in stuff that uses water to make notes and rhythms. If I imagine the sound of the Hydrum, because there is no other way to hear it, I am drawn to the idea that the Hydrums could be the percussion section of an Aeolian Pipe Dream orchestra. Say 4 Hydrums of various sizes and cadences —tympani to bongo — and a dozen APDs providing the wind and string sections. I believe we could prevent the annual breeding of an entire population of endangered sea birds or rare penguins by installing just a few of these combos on their preferred islands. The effects on shipping are predictable from the orchestra that doesn’t sleep, The Scylla & Charybdis Unchambered Sinfonietta. |

From your description 2fries I realise I think I've heard similar sounds before and also been fascinated. |
|
| |
[2 fries] Is the show over when the inner ‘striker’ bowl reaches the bottom of the ‘bell’ bowl? Do you need a mechanism to raise the striker into ready position to continue the presentation? |
|

I've been playing with this in sink this morning - one big glass bowl and a couple different sized plates. It *is* an interesting sound - but mine give more of a warbling dingdadingdadading than pewpewpew. Maybe US dishes are tuned differently than CN. |
|
| |
I was uncertain weather the change in notes was produced by the shape of the bowl or the amount of water beneath the descending plate, so I tried a little experiment with the same bowl and a wooden spoon for a striker.
It was most certainly the pressure waves made by the descending plate which made for the 'reverb' effect that my ears liked so much.
Tapping the spoon at various height inside the bowl makes notes but they are singular tones with no warble. |
|
| |
I think that the echoes of the sound waves created beneath the descending plate bounce back and forth at an increasing frequency before escaping and produce slightly off harmonic tones with miniscule time lags after the ear has registered the initial sound. |
|
| |
Then some guesses ... a flat plate or a curved one may sound different, also depending on the degree of curvature, and if the plate is sinking with concave versus convex side down. |
|
| |
That will be my next set of experiments, when nobody is around to ask what the heck I'm doing. |
|
| |
That was my next thought.
The salad plate was ceramic with an outer unglazed base ridge and then three more concentric ridges underneath about mid-way to the centre. |
|
| |
The shape and size and curves and wave pattern might accidentally be doing some cymatic resonant musical thing. |
|
| |
<shrugs> I just know it sounds sweet. |
|
| |
StarWars laser whale-song-ish like.. |
|
| |
As long as it isn't really the whale probe from Star Trek IV, The Voyage Home. |
|
| |
If someone dared to think it up it exists in some reality. |
|
| |
More specifically, I'm thinking of the sound of a frying pan cooling off while balanced on the narrow metal surface between two sinks, and rocking from side to side as it cools. Maybe that's a different kind of "pew-ew-ew". |
|
| |
I have some stainless mixing bowls that have become very interesting musically. If I œ fill one for the cat water and happen to knock into the wall or put it down a bit roughly I will get a warbling note that is short-lived but very engaging, like someone playing a saw. |
|
| |
This arrangement from [2 fries] seems to prolong that vibration as the plate descends and beats on the bell portion. |
|
| |
A lot of variables here: the size relationship of the plates/bowls. The volume of water. The depth the striker falls. Even the material and thickness of the striker and bell parts. Even the fluid viscosity. Would gasoline work better than water? |
|
| |
I can’t help but wonder if the very softest sounds can be amplified with a contact mic, as I hear the warbling fade but not entirely. Still need to get that striker back into ‘ready’ position. |
