Abstract

An electronic metronome includes an adjustable oscillator driving a first frequency divider, a crystal time base driving a second frequency divider for generating a pair of audible frequencies, a standard pitch frequency and reference (time base) frequencies, a frequency counter coupled to the output of the adjustable oscillator for counting the output of the adjustable oscillator, a digital display and display stabilizer circuitry for displaying the count of the frequency counter, a gate driven by the first frequency divider for programmably serially selecting one of the pair of audible frequencies at a rate determined by the output of the frequency divider, a selector switch, three visual indicators, and a programmable counter coupled to the selector switch and visual indicators for providing various sequential time signature displays and an audio amplifier and speaker for providing an audible beat patterns. The metronome may be adjusted to provide a wide range of beats per minute which is displayed on the digital display. Various beats per measure patterns such as single meter, duple meter, and up to and including sextuple meter are displayed in various distinct patterns by the three visual indicators with accompanying distinct audible rhythms.
