ABSTRACT:
The specification discloses a musical tutoring device for teaching a wide variety of rhythms and tempos. The device includes a housing. A keyboard is mounted on the housing and includes an array of numerical switches, each corresponding to a different digit and selectively operable to enable the operator to input a musical tempo value, time signature value and a starting location. The keyboard further includes an array of musical note switches, each corresponding to a different musical note value and selectively operable to enable the operator to input a predetermined sequence of musical note values of a musical composition. Storage circuits are provided to store the tempo value, time signature value and musical note values. Circuitry is provided to produce a sequence of tones, the duration and spacing of the individual tones of the sequence corresponding to the stored musical note values. The rhythm and tempo of the composite tone sequence are dependent upon the stored tempo and note values. The device enables the operator to hear and immediately reproduce a sequence of tones representing the input sequence of tempo and note values.
