    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.
