Michel Gagne visualizes jazz with Sensology:

The creation of this film was a true spiritual and artistic journey. Sometimes, I felt like I was channeling the images. I did no storyboards and virtually no preliminary work. I animated in a stream of consciousness, one frame at a time at a rate of 30 frames per second. The shapes revealed themselves as I listened to the music over and over again. The process was intensely focused and required large amount of concentration. I was becoming part of the music and expressing my creativity at its rawest and most primal.

Like Kandinski tought us, every shape and sound has a equal vibration in the soul. When Paul Plimley saw a portion of the film for the first time, he said to me with tears in his eyes, “It’s like you read my soul.”
Sensology was handdrawn (painted) with a Wacon tablet at first, and later, a Cintiq, using Adobe Photoshop. The drawings and frames were then composited and manipulated in a 2D software called Animo. There is no vector animation at any point in the film.
