Why do the Fourier components of a piano note shift away from the harmonic series?
This comes from me answering a question about functionally modeling a piano playing a middle C note in Mathematica.
I figured the note would consist of the fundamental frequency
f0 ~ 440 × 2−9/12 Hz ...

Is there a system behind recorder fingering charts or do people just memorize them?
I'd like to understand how recorder fingerings work, e.g. for a Baroque alto recorder. Let's say you know which holes are open, which ones are partially open and which ones are closed. How can you ...

Does natural amplification TRULY exist in acoustics or does it have to be turned into an electrical signal first?
I have seen people claim these two scenarios as being possible acoustic amplifications. My question is, are they TRULY amplification or are there any other types of acoustic amplification in existence....

Brass instrument lengths
I assume (perhaps wrong), that the fundamental frequency of brass instruments can be calculated with the wave equation:
c = lambda * f,
WHERE:
c = the speed of sound. I calculated this to be 349 m/s ...

Piano oscillation on a single string
Why is that when the hammer hits only one string on the piano, there is an oscillation and not a solid note throughout. I hear it like a wave of sound, not an absolute pitch. It doesn’t happen on ...
