The Octave
The Infinite Loop. Same note, different pitch. Discover why the musical alphabet repeats itself.
What is an Octave?
You already know the alphabet (A-G). But what happens after G? It starts over at A.
An Octave is the interval between one musical pitch and another with double its frequency.
Think of it like a color. Dark Blue and Light Blue are different shades, but they are both still "Blue". In music, A1 (Low) and A2 (High) are different pitches, but they are both the note "A".
The Science: Frequency Doubling
This isn't magic; it's math. A note's identity is determined by how fast it vibrates (Frequency).
- A1 = 55.00 Hz
- A2 = 110.00 Hz (Doubled!)
- A3 = 220.00 Hz (Doubled again)
- A4 = 440.00 Hz
- A5 = 880.00 Hz
Visualizing the Loop
When you play an octave, the sound waves fit perfectly inside each other. That's why they sound so stable together.
A1 (Low) and A2 (High) overlapping.
Hear the Difference
Listen to A1 moving to A2. It sounds like the "same voice", just higher.
