Abstract

A new modification of the Seashore tonoscope has been developed, similar to the phonograph form already described, using the phonograph motor as a source of power but having a new scale which covers a whole octave, in steps of tenths of a tone. The instrument may be read in terms of twentieths of a tone. These units were chosen because they are close to the sensory limits for interval discrimination and because such units are comparable from one octave to another.
