Sounds of Music C
If the frequency of the note C3 is 125 Hz, what is the frequency of A♭4?

Re: Sounds of Music C
I got 397 Hz, using frequency of a note = known frequency * (1.059463...)^number of halfsteps, which was 8 from C4 (250 Hz)terence.tan wrote: ↑September 7th, 2019, 9:20 am If the frequency of the note C3 is 125 Hz, what is the frequency of A♭4?

Re: Sounds of Music C
You’re tuning a bass guitar and for some reason have an obsession with knowing the tension of your strings. How much tension will you need to apply to your top string, G2, so that it is tuned properly if it’s 90 cm long and has a mass of 16 grams? (G2 = 98 Hz)
(Tried to make the numbers at least somewhat realistic lol)

Yea, I got 553.19 N specifically, but still good. Your turn!

Re: Sounds of Music C
Since smayya337 had the right answer but no posts have followed, I suppose it wouldn't hurt to start this up again.
Alice and Bob are playing a duet. Alice is supposed to play a note at 110.0 Hz and Bob is supposed to play a note at 164.8 Hz, but Bob accidentally plays his note 50 cents sharper than he is supposed to play it.
(a) What frequency does Bob actually play?
(b) If the interval between the notes is supposed to be a perfect fifth, Alice and Bob are playing most closely in what system of temperament? (A) Pythagorean (B) 12-tone equal (C) Just intonation (aka 5-prime) (D) All of these could be correct

(b) I’m not so sure, but I think it might be D. all of the above, since the frequency ratio is always 3:2?
