Question: are harmonics and octaves the same?
Answer: A harmonic is a frequency that is a whole number multiple (2, 3, 4 etc) of some fundamental frequency, and an octave is double the fundamental. ... An octave is a note that is 8 notes apart from another in a major or minor scale. E.g. low C to the next highest C. A harmonic is part of the sound of a (fundamental) note.
