• sound is contemporary: its life is momentary. sound exists only for real-time perception.
• music (as organized sound) lives on in the memory of human listener.
• memory exists because human beings are alive; each has his own history (life) as a background.

here i refer to sound and to music: music is made of/with sounds, we all know this simple truth. but most of the inventory of existing music isn’t made of sounds; it consists of written pages. music history is the history of musical writings (scores); but musical writing was invented just to synchronize sounds.

because the perception of sound (audition) is not strictly directional (it’s a very astigmatic sound-vision) we have a compelling polyphonic perception.

when composers have wanted to be the primary performers of their own music, polyphonic keyboard instruments - like organ and piano - have reigned as the kings of instruments, and many composers were indeed good keyboard players. but to develop a full and complex polyphonic sound they always needed many instruments or voices playing at the same time, and until the arrival of multi-track recording technology, the only way to realize such a goal was by writing a score.

this could be the reason that although we know music is made of sounds we disregard the fact that a musical composition is nothing more then a long, complex, well articulated single sound; it is a unique object like a painting, a sculpture or a building. musical writing imposes a lexical vision (audition) of music but more and more, the listener’s consciousness realizes that form has meaning only because it resonates in our internal perception, connected with memory.  or not?
