Octaves and Pitch Classes
- Octave comes from the root word related to the number eight.
- Despite having only seven unique pitch names, the octave is based on the number eight.
- Counting up eight pitches from a starting note results in the same pitch class, demonstrating the concept of an octave.
- Octaves have a very similar sound and are related by a distinct similarity in their sound.
- Notes in different octaves, but with the same pitch class, share a similar sound and are often referred to as the same note (e.g., A in different octaves).
- The relationship between notes in an octave remains the same whether going up or down in pitch.
- Octaves are important in music due to their similar sound, making them harmonious and non-dissonant when played together.
- Adding an octave to a melody can add interest and variety without introducing dissonance.
- Octaves relate to pitch classes in that they share the same pitch class, but differ in pitch (e.g., A in different octaves is the same pitch class).
