Abstract
An electronic metronome device producing precisely timed and tuned rhythms and pitches that are pre-programmed to correspond to specific scales or modes, arpeggios, chords, and etudes. A combination of microprocessor and user interface (34, 30, 28, and 26) stores these musical exercises and retrieves them from an electronic memory (36), inputs them to a signal processor (42) for amplification and modification, and outputs (40) them to speakers (12), optical displays (24), audio outputs (18), etc. A volume control 20 and balance control 22 modify the audio signal coming from the speakers 12. The components, enabled either by an internal (battery) or external (plug) power source (44), are housed in a light and durable case for easy portability and user control.
