Theoretical Treatises (e.g., Musica enchiriadis)

Theoretical treatises like *Musica enchiriadis* are ancient scholarly works that explore the principles of music—such as scales, harmony, melody, and rhythm. Written in the medieval period, these texts serve as foundational guides to understanding how music is structured and performed. They often include methods for teaching music, notation systems, and explanations of musical concepts, helping musicians and students grasp the theoretical basis of the art form. Essentially, they are early manuals that codified musical knowledge, enabling a shared understanding and development of Western musical tradition.
