Musica Practica & The Grain of The Voice.

First time seeing the graphic scores I got the feeling that the song was a smooth jazz from the 50's from the vintage color pallette and geometric forms used in the interior home design of the time. But the song is actually a tech ambientation music. It is from 1958, as I thought, and was recorded in magnetic tape.

Lines are also used a lot to represent ligatos from one note to other and whenever extended from a basic note shape it emphasizes the duration and rhythm. The thichkness of the lines represent the dynamic in the intensity of the note and volume.

 

The graphic score comes with instructions and is a cell notation as it breaks the piece down in small sections that are perfomed one at a time, and as stated, read from left to rightI, with vertical alignment indicating simultaneity. In it, there are several different symbols that assemble road signs,. They are formed by basic geometric forms such as rectangles, circles, archs and arrows, arranged in different compositions  and painted in bright orange as suggested by William Gardiner (The Music of Nature, London 1832) to signify the trombone playing.
