👉 Centuples are a type of musical scale that consists of twelve notes. These notes are usually labeled as C, D, E, F, G, A, B, and C#, with each note being separated by one semitone (a half step) from the previous note. The name "centuple" comes from the fact that these notes form a complete set of twelve tones, similar to how the sixths and sevenths in the major scale form a complete set of twelve tones.
