"To understand music as a whole, you have to specify simultaneously its levels of reality, its semiotic character, and its communicative extension."

 

"Music takes place on a wide range of realities. They may be grouped into physical, mental and psychological levels."

 

"Molino’s scheme partitions the communication process into three instances: creator, work, and listener."

 

"... music is structured as a complex system of signs. This is not only a marginal aspect: Music is one of the most developed non-linguistic systems of signs."
