This invention is a display system for measuring and displaying, individually or simultaneously, the frequencies contained in a musical sound. A transducer coupled to the sound source produces an electrical signal representing the musical sound. The system receives the signal and separates and measures the frequencies of the individual tones comprising the sound. The measured frequency values are displayed as the frequencies themselves or as deviations from target frequencies. The system can utilize a local transducer with the display system or a remote transducer coupled to the sound source.
