Pitch Classes
Week 2
Introduction to Pitch Class
Pitches are individual tones with individual frequencies. The concept of pitch, then, does not imply octave equivalence. C4 is a pitch, and it is not the same pitch as C3. The same goes for D4 and D3, E2 and E1 and so on and so forth.
- Pitch classes are defined as a group/selection of notes with the same letter name but different octaves.
only a few of these pitches are audible to the human ear
The pitch class C stands for all possible Cs, in whatever octave position.
