comment Compare FM synthesis sound signal to equivalent additive synthesis signal
I suspect that the difference is due to the phases (+/- signs) of the component signals in the additive synthesis -- maybe try summing |a_n|*cos(w_n t), i.e. take the absolute value of the amplitudes.

comment Markdown for music notation fragments
If you are asking about it for this site then this is a meta question (and discussed most recently here meta.music.stackexchange.com/questions/2188/… ); This would be a good question for the main site if you're asking in general about approaches to enable music markup in websites, but, to me, it's not clear from the wording of this question that that is what you are asking about.

comment Physics behind why a bugle can play several notes, while a whistle only plays one note
What have you tried? -- e.g. wikipedia has reasonable discussion of whistles, inc. descriptions of the physic.

comment Singing the words to one song along with the music for another - what is this called?
@KilianFoth -- yes the musicological definition of parody en.wikipedia.org/wiki/Parody#Music would seem to be the answer for "what is the name of this"

comment What is melodic inversion and how to do it?
c d e g goes +2 +2 +2 semitones (c to d, d to e, e to g), so the inverted melody would go -2 -2 -2, so if you started on c, it would go: c b-flat, a-flat, g-flat (the inverted melody could start on any note).

comment What does it mean to play a note for half a second?
@thePetProjectProgrammer I never said 220Hz -- I pointed out the 220 oscillations to emphasize that there are still a large number of complete cycles even in one half of a second. The only time when you'll run into a problem is when the duration of the note is so short that it can't complete even a few of them.

comment What does it mean to play a note for half a second?
Since the ear effectively does frequency analysis an uncertainty relation applies en.wikipedia.org/wiki/Fourier_transform#Uncertainty_principle -- thus a very short short signal does not have a well defined frequency, rather is has a spread of frequencies.

I guess that I learned a rule of thumb that is slightly more stringent than you.

comment Classical examples of a 'fifth voice' or 'ghost soprano'
@jjmusicnotes This should probably be moved to chat -- this is my understanding of what is going on: combination tones do not exist /in the air/ (or more generally as any kind of mechanical oscillation). What is going on is that the pattern-matching mechanisms in the ear & brain detect 2f (and it's overtones -- this is the octave avbove) and 3f (and its overtones, this is one fifth above the 2f pipe) with the net result that the listener subjectively perceives that the pitch of that sound is 1f. This also underlys the way that church bells are tuned.
