In any art movement, the art has to move into a new phase - a filmmaker has a desire to make a film that is not like a previous film.

So people will come along and do new things and sometimes return to the spirit of an earlier age.

The process of art evolving is always one which has fascinated me.

The number of strokes to the inch controls the pitch of the note: the more, the higher the pitch; the fewer, the lower the pitch, the size of the stroke controls the loudness... the tone quality is the most difficult element to control, it is made by the shape of the strokes.

Animation is manipulating the difference.

And so my militant philosophy is this: to make with a brush on canvas is a simple direct delight-to make with the movie is the same.

Well rounded forms gives smooth sounds; sharper or angular forms give harder and harsher sounds.
