It has 41 tracks of sound, including woodwinds, strings, brass and a very large representation from different percussion instruments. These include bamboo wind chimes, wood blocks, xylophone, snare drums, timpani, bass drum, triangle, tubular chimes, thunder sheet , rocks, sand paper blocks, glass harmonica, glass wind chimes, piano, celeste, and kalimba. The music is represented by a computer file of MIDI data. Each note as it is played creates a rectangular strip located in a specific place over the landscape which is determined by time and pitch. Pitch is the y axis and determines how high it is placed in space.
Time is the x axis, going from left to right, so time says where the strip begins and ends in space.
The initial attack of the note, which is how loud it begins, determines the width, or z axis of the rectangular strip, which remains constant until the note ends. Further changes in loudness or softness are reflected in the saturation of the timbre color which is part of the surface of the strip. Each strip is also embedded with a texture map taken from the original pencil drawings of the landscapes. For instance, all stringed strips receive images which are taken from an endless line of mirrored desert floor hills and washes called Strings. The texture is taken from higher and lower positions in the drawing based on pitch information as in my 2D wall visualizations.
