****If the article is correct, only wind and string instrument can create undertone. ****
Yes, and we all know how authoritative Wikepedia is. And no, not just those instruments can create undertones.
The Wikepedia article is (as usual) very incomplete. The production of undertones does not require special playing techniques. They can (and are) be produced by the acoustic interactions of two or more fundamentals. In the example that I described, no special techniques were
needed nor used. Undertones occur naturally as part of the harmonic texture of music. They add timbral complexity to music.
****I tend to agree that below 30Hz is not really musically relavant. ****
Really?
****Sure, it adds ambience in some cases. By the low 20s it is more felt than heard. It is an awesome experience to hear a large pipe organ in a large cathedral. I have never heard that reproduced electronically 100%.
Perhaps it would take a room nearly as big as a cathedral to do it. The 16ft pedal on the pipe organ just makes a pressure and creates a certain mood and is always a relief when that low frequency sound ends. I think that is part of the mood too. I think some experiences like being in front of a large pipe organ need to be experienced first hand.****
Sounds like musical relevance to me. Below 30hz reproduction may not be absolutely necessary, but it is clearly relevant and adds a great deal.
