Wind Chime Length Calculator (2022)

If I was tuning wind chimes, I would probably use Just intonation, not equal temperament because a wind chime play in different keys.

Exceptional circumstances excepted of course.

> Exceptional circumstances excepted of course.

ECEOC?

I have used 'BOCTAOE' (but of course there are obvious exceptions) in the past, but, guilt by association, kinda stopped all that.

brudgers•1w ago
I write such things because the internet gonna' internet and I'm feeling too old for that shit.
JKCalhoun•1w ago
Had to look up "Solfeggio Healing Frequencies".

There are plenty of 9-hour long YouTube videos (example [1]) cycling through the frequencies. Apparently to be played while you sleep.

Nice, although a metric version would be helpful :D

Times inches by 25.4 for mm, there is 25.4mm in every inch.

https://leehite.org/Chimes.htm is the best source of information I've found on chime design and length. They go into great length about the lower octaves and how you can hear them (or not).
scrumper•1w ago
The linked site acknowledges Lee Hite actually. I suspect it's not a crowded field :)

The suspension point calc is particularly neat, I suppose putting it at a null node in the tube vibration so it doesn't damp it.

The clanky sounds of cheap bamboo or the high pitched screeching of tiny metal chimes are not pleasant. I have two sets of tuned chimes in my garden that are 1" diameter. They both have 6 chimes that are tuned as a set, but they are also tuned when heard together. One set has longer chimes than the other, so when heard together the chords are much richer.

I know it sounds bougie as hell, but it's really quite a nice effect.

aaarrm•1w ago
Where did you get them if you don't mind me asking

Also do you know the material of the metals? I wonder if it'd be worth it to have them in different metals for different timbres. Like two different instruments

You can play multiple chimes at the same time to get a feel for how they pair

SoftTalker•1w ago
Do they stay (relatively) in tune with temperature changes?
dylan604•1w ago
I'm in Texas, so we have warm, hot, hotter. I've never noticed a difference from temp changes. Whether it has an effect or not, I haven't noticed.
phkahler•1w ago
That seems like an argument for using the same material. Different metals will expand more or less with temperature variations. If they all chance a fixed percentage the tonal ratios should be preserved.
rossjudson•1w ago
Tuning matters! After my daughter complained about how the toms on her new drums sounded like crap, I bought a Tune-Bot (drum tuner), asked Gemini to help me make her toms sound like Dirty Loops, and got busy.

A few hours later, she pronounced them to be "not bad". Win! I wasn't going to get higher praise out of a teenager anyway.

bloggie•1w ago
I don't see the unit shown anywhere, is the calculator unit-agnostic?
