For context, bass guitar strings are tuned 3 octaves lower than that. The frequency of the A string is 55 Hz. You can’t even reach 220 Hz using the 12th fret on the highest (G) string. Tuning a bass A string to 8 times the frequency would require increasing its tension almost 3 times. The guitar body should survive such forces but the string will snap long before you reach 110 Hz.
Let me just tune up real quick

Or you can just use harmonics.
ChaoticNeutralCzech@feddit.org 3 months ago
I think that would make a standing wave with a series of nodes/antinodes on the string, and how well it works would strongly depend on where the tuning fork is along the string. This has the potential to be more interesting but it’s not as easy.

Yeah, you can’t tune your bass’s A string to a 440 Hz A. Lol
With that being said, the phenomenon the meme is referencing is called sympathetic resonance. It is not limited to matching intervals, but will resonate sympathetically at any frequency in the material’s harmonic scale. Any A will make any well-tuned A string resonate, it just may be very low amplitude.

As Frozengyro@lemmy.world mentioned, you can have interesting results by using harmonics - tones that are a whole (k) multiple of the base frequency because then the string vibrates in a standing wave forming a series of k+1 nodes (including ends) and k antinodes equally spaced across its length. Such notes are:
Closest note Freq. Harmonic Relation to A A1 55 Hz base A2 110 Hz 2nd octave above A1 E3 + 2 cents 165 Hz 3rd perfect fifth from A2 A3 220 Hz 4th octave above A2 C#4 - 14 cents 275 Hz 5th major third from A3 E4 + 2 cents 330 Hz 6th perfect fifth from A3 G4 - 31 cents 385 Hz 7th far from a note on the chromatic scale A4 440 Hz 8th octave above A3 B4 + 4 cents 495 Hz 9th major second from A4 C#5 - 14 cents 550 Hz 10th major third from A4 D#5 - 49 cents 605 Hz 11th very far from a note on the chromatic scale E5 + 2 cents 660 Hz 12th perfect fifth from A4 F5 + 41 cents 715 Hz 13th very far from a note on the chromatic scale G5 - 31 cents 770 Hz 14th far from a note on the chromatic scale G#5 - 12 cents 825 Hz 15th minor second below A5 A5 880 Hz 16th octave above A4 You could continue forever but frequencies above that will have a very weak response.
Yes, you will get some resonance on non-integer multiples but way less.

Tbf they meant relative to the Stuttgart pitch. Humans would also refer to an orchestra tuning to concert pitch “A440.”
Windex007@lemmy.world 3 months ago
I don’t think the AI meant anything.
funkless_eck@sh.itjust.works 3 months ago
“They” being the sources that the AI ingested to produce this output. AI is a word association machine, not a research tool. If people (“they”) call “tuning relative to A4=440Hz” “tune A to 440” AI will repeat it.
I’m just saying, while the OP is technically correct, one wouldn’t apply the same requirements on conversation with a human, which AI is built on.
CuddlyCassowary@lemmy.world 3 months ago
I understand your point, but isn’t an orchestra ACTUALLY tuned to 440 (or 442 sometimes), because it’s usually a violin or oboe they’re tuning from? Like yeah, my bass isn’t going to be at 440, but the pitch I’m listening to while tuning is 440.
bstix@feddit.dk 3 months ago
You’re right. Orchestras often tune to the oboe, because it can’t easily be tuned and usually stays in tune in conditions that would make other instruments go out of tune.

Y’know, you’re definitely right. But if Copilot were really useful it could have explained that.

AI always does this shit.
“Do X thing”
“I don’t think that sounds like a good idea”
“You’re right! Don’t do X thing. Do Y thing instead”

it’s so fucking defeatist, but then again the alternative is the ai clowning me, which I actually experienced, NOT FUN EITHER.

The way they immediately give up is funny to me. I know people like that tbh.
