Abstract: An exercise device for compression exercises is adjustable in height and in compression force. The device includes a central housing and a plurality of plungers extending from a top side. A support member is attached to the housing on a bottom side. The support member is movable longitudinally relative to the housing and plungers from a fully retracted position to a fully extended position and is lockable in a plurality of intermediate longitudinal positions to vary the height of the device. Each plunger is operatively associated with an internal bias member that biases the plunger away from the housing. Resistance force on a plunger is adjustable via changing tension of the associated bias member with an adjustment knob to finely adjust tension. An installed bias member is removable and replaceable with a different bias member to coarsely adjust tension.

Abstract: Bowing platforms are disclosed for use in playing a bowed musical instrument without reliance on strings. A bowing platform includes a support and a track that replace the strings, bridge, and tailpiece on a conventional bowed instrument, to provide an alternative vibrational bowing surface. The bowing platform can be attached to a conventional fingerboard or to the body of the instrument. In one aspect, the bowing platform is useful as a bow guide to improve bow technique by restricting the player's bow angle to be within a desirable range, while still allowing for natural arm movement. The bowing platform can be further equipped with piezoelectric sensors to sense bowing motion and to create sound electronically in response to the sensed motion. A stringless bowed instrument includes a bowing platform, bowing sensors, and pitch sensors that sense finger placement along the fingerboard.

Abstract: An apparatus is provided, for calculating a practice time. The apparatus is used by a user to calculate such practice time that he/she requires to improve his/her playing technique to reach a predetermined progressing level at the playing technique. In the apparatus, a progressing-level evaluating unit evaluates a progressing level of a playing technique of the user who operates a playable unit. A history of the evaluated progressing level is recorded in a progressing-level recording unit. An operation-number counting unit counts the number of operations executed on the playable unit by the user every unit time. A history of the counted number of operations is recorded in an operation-number recording unit. A practice-time calculating unit calculates the practice time based on the history of the progressing level recorded in the progressing-level recording unit and the history of the number of operations recorded in the operation-number recording unit.

Abstract: A wind instrument training device is provided having a housing with a mouthpiece opening in one end and an air exit opening in an opposite end. The device also has two sliding members movable within the housing, each having an air passage and each extending through opposite side openings in the housing.

Accordingly, a user can realize advantages of the invention and utilize practice methods while the user is “on the go,” riding on a bus, watching television, waiting in line, etc.

Abstract: A method is presented that selects a musical exercise to be performed by a student based on the assessment of previous performances of musical exercises within a syllabus. The musical exercises within the syllabus that have been performed more poorly are more likely to be selected. This enables the student to practice the exercises that are most in need of practice without having to wait for feedback on progress from a teacher and thus accelerates the learning process.

Abstract: A method is presented that allows feedback to be given on a musical performance without restrictions on the performance in terms of quality of intonation, tempo, or specific note order. Based on standard musical exercises, the ability to rate a performance is tolerant to repeated and/or omitted notes, to varying tempo and to systematic tuning errors. The method is suitable for use on mobile devices and may provide real-time feedback to allow the performer to adjust their performance or monitor their progress during the performance. Since a wide range of proficiency is able to be rated to give an indication of how well the performer executed a musical exercise this allows very inexperienced musicians to feel a sense of accomplishment when practicing outside the teaching environment as well as giving more accomplished musicians the feedback they need for continuous improvement.

Abstract: A musical performance training apparatus of the present invention receives an input of a note of a musical sound; stores a keying frequency received during a predetermined unit time to be associated with a practice status variable (such as a single-hand partial practice); evaluates motivation change of a user based on the keying frequency stored for every identical practice status variable; evaluates a musical performance technique level change of a user based on the keying frequency stored for every identical practice status variable; and generates advice based on the motivation change thus evaluated and the musical performance level change for every practice status variable.

Abstract: A exercising and conditioning device is used in the chord hand of people who play a guitar or similar stringed instruments. The device has a body with an upper surface containing a longitudinal groove. At least one string is tensioned within the groove below the upper surface so that, when the body is held in a hand, all the tips of fingers of that hand may extend into the groove to depress the string. Depressing the string builds callus pads on the ends of the fingers and strengthens muscles used to depress the strings. Placing the string within the groove assists in guiding the fingers to the best position on the string.

Abstract: A fretted stringed musical instrument is provided with channels which can removably accommodate frets. In a preferred embodiment of the invention, the channels are provided at locations where it is sometimes, but not always, desirable to have a fret.
