"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"

This quote by Norman McLaren is describing the art of computer animation. The number of strokes to the inch is an action of the pitch of the note, which is the regularity of the sound. The even more strokes per inch, the greater the pitch; the fewer strokes per inch, the lower the pitch. The dimension of the stroke manages the volume of the noise. The tone high quality is one of the most difficult aspect to regulate, as it is identified by the form of the strokes. This suggests that the animator needs to be exact in their technique in order to produce the desired noise. The animator must have the ability to control the variety of strokes, the size of the strokes, and the form of the strokes in order to create the preferred sound. This quote emphasizes the relevance of accuracy and also method in animation, as the animator must have the ability to manage all of these aspects in order to create the wanted noise.
