Generating music using a picture and a transform system

This paper introduces a method to generate music using a picture. We outline the transform system we created to do so. We analyze pictures as visual information, and music as acoustical information. We find they have features, such as continuity, in common. We create a transform system based these common features and output the music using MIDI (Musical Instrument Digital Interface). We consider the fundamental features of music when we create the transform system. A stream of music is repetitive, has contrast, and variation. However, in general, pictures lack these features. We generate music by combining rhythm and modulated rhythm. This paper shows how to create the transform system, the process of generating music using a picture, and the algorithms involved. By showing the output´s high degree of freedom, we prove that this system can help the composer compose. The composer can quote some rhythm or melody of generated music, or can obtain inspiration to compose when listening to the outputs.
