Abstract: A musical performance training system includes a transmitter which transmits training musical note data for training musical performance, and a receiver which receives the training musical note data from the transmitter and instructs a trainee to practice a musical performance based on the received training musical note data. The transmitter produces musical note data based on a musical performance, for example, at a keyboard. The musical note data is converted to training musical note data by reducing velocity data contained in the produced musical note data, shifting pitch data in units of an octave, and changing the timbre and pitch data to respective particular values. If the musical note data is produced by a special key operation, control data which instructs the trainee to perform a pedal operation is added to the converted musical note data. The receiver displays or audibly outputs a performance instruction based on the received training musical note data.

Abstract: The present invention is directed to an instructional method based on the concept that as a student learns to perform a mental task consisting of a set of elements or steps, whether conceptual or concrete, the student develops a distinct mental connection or path for every element related to the primary mental task being learned. For example, as a student learns to type a particular key on a keyboard, (the primary mental task), the student develops a distinct mental impression for every typing key logically associated with the first key. In other words, a distinct connection or path is defined as a link between two or more elements, one key being a primary element, the other being a related key connected to the primary key by a logical mental step. The present method is also useful for learning a musical instrument, a foreign language, mathematics, test taking skills, and the like logical though processes.

Abstract: The invention is a music teaching method designed for the student of non-pitched percussion instruments incorporating two major components. First, a limited selection of basic percussion exercises and variations written for one or more percussion instruments is printed on opaque music manuscript paper or other music display media. Finally, a series of overlays including preprinted, complimentary percussion music exercises is provided for use in combination with the aforementioned basic percussion exercises. The overlays may be alternately superimposed in a functional relationship with the basic percussion exercises to create hybrid percussion exercises having adequate visual representation of the repetitive rhythmic patterns inherent in percussion music. Thus, an exhaustive collection of percussion exercises may be provided in a reasonably sized volume, reducing the cost of a more cumbersome printed volume that would be impracticable to publish and market.

Abstract: A pulsed-tone timing method. Pulsed audible guide tones are activated at an initial pulsing rate. The pulsing rate is manipulated so as to repeatable (i) increase the pulsing rate over a time span to an intermediate pulsing rate and (ii) abruptly drop the pulsing rate to a decreased rate between the intermediate pulsing rate and a previous rate, until a predetermined final pulsing rate is reached. The pulsing rate can be manipulated such that each subsequent intermediate pulsing rate pulses at a faster rate than previous intermediate pulsing rates. The method can be used in many activities. For example, a reader can read a line of text per each guide tone while keeping pace with the specifically timed rate increases, thereby increasing reading effort and reading speed.

Abstract: This invention features a U-shaped hole shield, for isolating one harmonica hole at a time, and is sufficiently long to span the lips of a harmonica player. In the center of the face of the U-shaped shield, there is a rectangular aperture with dimensions substantially identical to the dimensions of the rectangular holes of a harmonica. When the shield is placed in position on the harmonica, the rectangular aperture of the shield can be aligned with any desired rectangular hole of the harmonica. Thus, one, and only one, hole of the harmonica will be exposed, while the adjacent holes will be covered, and shielded, by the shield. The musician's lips can be placed against the shield, centered about the aperture, and without the need for the use of the tongue, a single note can be sounded with ease, simply by blowing into, or drawing air out of, the exposed hole. The movement of the shield is controlled by the lips, and the hands move, or slide, the harmonica, sideways, in either direction, relative to the shield.
