For @123tay5o! I was really confused as on what an octave was so I looked for the definition on Google and here it is if you don't know what octave means: In music, an octave (Latin: octavus: eighth) or perfect octave (sometimes called the diapason)[2] is the interval between one musical pitch and another with double its frequency. The octave relationship is a natural phenomenon that has been referred to as the "basic miracle of music", the use of which is "common in most musical systems".[3] The interval between the first and second harmonics of the harmonic series is an octave. And... I still didn't understand so I just got images from Google. I'm sorry... I'm dumb.
