ABSTRACT:
An electronic, tempered scale tuning aid employs a transducer and signal processing means to detect and amplify a signal to the level required by digital logic circuits, which circuits are used to gate a precisely determined oscillator, which is arithmetically related to the operating range of the instrument through a counting and analyzing apparatus. By scaling the measured count, a display in musical notation of both absolute pitch and intonation error is obtained.
