Octave vs. Pitch
The interval of doubling frequency versus the perceived highness/lowness of a note.
The comparisoni
“A high OCTAVE is one octave higher (double frequency). PITCH is the more general term for highness/lowness. Different concepts.”
The ruleii
¶
OCTAVE = 2× frequency. PITCH = highness.
PITCH: how high or low a note sounds (frequency-based). OCTAVE: a specific interval where frequency doubles (A4 = 440 Hz, A5 = 880 Hz — one octave higher). Notes one octave apart sound "the same" because of frequency doubling.
Memory aidiii
Remember it like this
Octave = doubled.
