Extrusions in C Major is an experiment in music visualization. The composition used for these images is the Trio C-Major for Piano, Violin, and Cello by Wolfgang Amadeus Mozart. The program analyzes a range of note characteristics such as value, velocity, duration, and overall tempo. The notes of the three instruments are differentiated by color: white for piano, yellow for violin, and blue for cello. The faces of 3D primitives are the seed for these structures. These facets are extruded, scaled and rotated based on the attributes of the notes parsed from the musical composition.
