Looks like it's been built: https://www.youtube.com/watch?v=agInwu6Ojdg

(makes sounds, but keywork isn't there yet).

If you enjoyed that one, you may also like this recording (subcontrabassoon comes in at 0:26). https://www.youtube.com/watch?v=SGSh34z1SrI

We live in an age where combining music, software, and signal processing can let you do some amazing things. I can imagine a high-fidelity simulation of this instrument's timbre before it's ever built, by using the mechanical CAD model to produce an acoustic model, and then modeling the response of the wood to an incident acoustic wave.

It's already sounded it's first notes a while ago. Sorry to spoil the fun.

The planned sounding range of the subcontrabassoon is from A−1 (13.75 Hz) to (at least) F2

dane-pgp• 4 years ago

The thought of a note having a frequency of just a few Hertz reminded me of an old video I watched, which explained that all tones can be thought of as rhythms (and chords can be thought of as polyrhythms):

Great video, thanks!

Good news is that since I'm been experimenting with the incomplete prototype, I've been able to play up to at least Eb3, and will likely get F3 on the redesigned 2nd prototype. That gives it roughly the same range as the bassoon (just two octaves lower), all without the need for a dedicated altissimo vent.

elevaet2• 4 years ago

Very cool, congratulations! Does it take a lot of breath to play those lower notes?

This reminded me of a very hip recording of Anthony Braxton playing Donna Lee on contrabass clarinet:

Not to be confused with the subcontrabass flute, which can be heard (for example) in Justin Bell's soundtrack for The Outer Worlds [0] [1].

I remember going to a flute event in Chicago back around 2000 and in the exhibit hall, there was a bass flute¹ that a few people picked up and couldn’t get a sound out of—later, I was on the other side of the room and someone (who likely had previous experience with the bass flute) picked it up and played a lyrical line on it and it was one of the most beautiful things I’ve ever heard.²

⸻

1. While called a bass flute, strictly speaking a bass flute should be called a tenor flute as it sounds a fifth below the alto flute which sounds a fourth below the concert flute. The piccolo plays an octave above the concert flute and there are intermediate flutes pitched a fifth above the concert flute and also a whole tone above it.

2. At the time, a bass flute seemed an improbably expensive instrument that I could never afford to buy. It occurs to me that now that I’m older and more financially secure, I could conceivably afford to buy one and learn to play it.

I got a supposedly used Jupiter for $1500 on eBay a few years ago, so yeah! Worth it.

fortran77• 4 years ago

Not too many people would confuse a flute with a bassoon.

tomcam6• 4 years ago

[0] Damn. Scrub to 1:00 if you want the real tea. In the first part he’s playing very high, in standard bass flute territory. At the minute mark it sounds like a string bass. The amount of air you need to push through an instrument that size has to push some kind of anatomical limit.

Kaibeezy• 4 years ago

“amount of air”

Is it more air than, like, a tuba, or whatever would be a more familiar so-low instrument? Would it be cheating to add an assist like on a bagpipe? What about mechanical airflow like a compressor or air conditioning vent?

robin_reala2• 4 years ago

…or the subcontrabass recorder, e.g. https://www.kunath.com/en/Generalueberholung-Subkontrabass-P... or https://www.dolmetsch.com/millennium.htm .

I have a near obsession with these instruments, and would love to try to build one. Excellent recording of this awesome recorder in action here: https://www.youtube.com/watch?v=JIesMapxaOs

I went into college as a bassoon performance major and came out as a math major. This is so incredibly amazing to me and is one of the most serendipitous posts I've ever seen on HN.

It looks from the diagrams like the plan once the keywork is done is to have some of the keys operate what look to me to essentially be bicycle cables (Bowden cables), which for some reason I find totally delightful.

madcbsnist4• 4 years ago

The original plan was to use Bowden cables for some of the low register notes, but I've since redesigned those to use more robust and stable traditional linkages.

Bowden cable linkages work well on some woodwinds, specifically those made by Wolf or Eppelsheim. However, on those instruments they're used for harmonic vents; tiny keys that are normally held shut by spring action, where the cable linkage only needs to open the key slightly, and which often need to be placed in positions where traditional keywork would be impossible (like on the bocal). For low register notes, the holes are large and on the main bore, most keys are open by default and must be closed a precise amount for proper sealing, and even those that are closed by default need to be opened a precise amount for proper intonation. So in the end I believe Bowden connections are unnecessary for the current design (unless I decide to add an altissimo vent to the bocal).

Makes sense, thanks for the clarification!

OP: your username brought me a big smile this morning. Yes it is totally out of topic, but thank you.

techdragon• 4 years ago

This kind of sound is why I don't think I'll ever be rid of the desire to build a calliope, or more technically a calliaphone, but not being a musicologist, I'm not sure if that also technically makes it a pipe organ.

A special few instruments can reach down the frequency scale and just whack you with a note so low it feels like a force of nature is coming out of the instrument. And I'm always delighted whenever I come across a new one.

zwieback• 4 years ago

That guy who got into a fistfight with Bach: bassoon player. Just imagine what would have happened if he was a subcontrabassionist.

madcbsnist4• 4 years ago

Thanks so much for sharing my project. If any of you have questions, I'm happy to do my best to answer them.
