- What is an octave? - Music: Practice Theory Stack Exchange
An octave is simply an interval created by the use of the factor 2 instead - e g if we started with our 100Hz note again, and we wanted to go up an octave, we would double the frequency, taking us to 200Hz If we wanted to go down an octave, we'd halve it, taking us to 50Hz Why is this factor of 2 so special?

- Why do clef octave changes use 8 and 15? [duplicate]
Here, there's a series of octave clefs listed as using 8 and 15 to alter the clef by one or two octaves respectively My understanding of music theory is that there are 12 notes in an octave, and only 7 whole notes in a typical scale
- Why are there twelve notes in an octave? - Music: Practice Theory . . .
It makes me wonder if the 12-semitone octave sounded good before the advent of "music as we know it" or if it is something of an acquired taste, in which case alternative breakdowns of the octave could be adapted to, like in the case of western vs indian vs east asian music
- tuning - Was the term octave coined after the development of early . . .
Was the term “octave” coined after the development of early music theory? No As shown below, it was already in use by the 11th century to denote the musical interval (although the principal name for the interval at that time seems still to have been diapason) What system was in use in medieval Europe when the term octave arose, and what did the term octave refer to? I'm a little hazy on
- notation - Why transpose at the octave? - Music: Practice Theory . . .

- Simple way to add an additional octave in Musescore?

- Why is a doubling of frequency called an octave?
There are many longer answers here on this topic But the gist is that like the octave (frequency ratio 2:1), small whole-number ratios of frequencies are often heard as "consonant " So the ratio 3:2 between frequencies sounds good (and, as noted, creates an interval called a perfect fifth), as well as the ratio 4:3 (the so-called perfect fourth)
