Instruments that play <= 40Hz (E1) include double bass (either standard or with C extension), bass clarinet, and contrabass clarinet.
Percussion also generates frequencies under 40Hz.
- mrob 4y agoAnd percussion generates sharp transients, which require frequencies below the steady-state fundamental frequency to be reproduced accurately: https://en.wikipedia.org/wiki/Uncertainty_principle#Signal_processing https://en.wikipedia.org/wiki/Uncertainty_principle#Signal_p...
- mechanical_bear 4y agoAlso octobasse and subcontrabass saxophone…although most people won’t get a chance to actually hear those in person.
- Nition 4y agoPiano too if there is one. The fundamental frequency of the low A is 27.5Hz. A Bosendorfer Imperial grand piano goes down to C0, 16.4Hz. If there's a pipe organ with 64' pipes you can hit 8Hz. Not many of those though.
- aidenn0 4y agoPlenty of organs go below 20Hz though, and even an otherwise good sound system starts to struggle around 40Hz if it's not built specifically for playing such notes.
- Blackthorn 4y agoDumb question but how is the piano capable of generating these frequencies? I thought the strings couldn't get nearly long enough and the low frequencies that you heard from piano were just psychoacoustics.
- quercusa 4y agoThe bass strings are wound with copper wire so that the mass is much higher and the resonant frequency much lower.

- Nition 4y agoThe amount of space needed for a certain frequency in air is different to the length needed for that same frequency in a wire. It might help to see the formula, which is: Frequency = sqrt(tension/(mass / length)) / (2 * length) So length, tension, and mass are all factors. Modern upright pianos also string the bass strings diagonally to give them a bit of extra length. Having said all that, the same bass notes on longer pianos that can fit longer strings sound more sonorous. I'm not sure exactly why that is. For an extreme example see for instance the Alexander Piano[0], or the Klavins 370[1].

- dehrmann 4y agoI can almost imagine seeing the low bass string on the longest piano vibrating. The frequency is so low you can pick hear the peaks and valleys.
