Attempts of teachers of voice and violin to improve the pitch intonation of their pupils have been exceedingly wasteful of time, due to the tendency of the ear to be either too inaccurate or too easily satisfied in the matter of small differences of pitch. The tonoscope, an instrument now available for use in the music studio, provides an immediate objective visual check on the accuracy of produced tones and further motivation for the improvement of pitch intonation.
