The interval between two notes where the higher note has exactly double the frequency of the lower. The two notes sound like the same pitch at different levels.
From the Latin octavus meaning 'eighth' — in a diatonic scale, the octave is the eighth note (C-D-E-F-G-A-B-C).
Understanding octave is essential for reading and writing music accurately. Whether you are a beginner learning to read notation or an experienced composer, knowing how this musical element works improves your musicianship.
