Who discovered the musical note value pyramid?

The musical note value pyramid is not attributed to a single individual as a formal "discovery," but rather it is a conceptual tool used in music education to illustrate the relationships between different note values (whole notes, half notes, quarter notes, etc.). This pyramid helps students understand how these values relate to one another in terms of duration and rhythmic structure. Various educators and music theorists have used similar concepts over time to teach rhythm and notation.
