Ways to tell them apart:
The word scale can refer to a range or series of notes, while octave specifically means a series of eight notes.
Octave is always tied to the number eight—there are eight notes in an octave in music.
A scale in music can vary in the number of notes and can refer to major, minor, or other types.
The word scale might remind you of sizes or levels, as in scales of measurement, because it's about progression.
Consider octave comes from octo, the Latin word for eight.
