Embodiments are directed to a musical instrument having buttons, where the buttons determine the magnitude of the interval by which the melody will jump from the last note played. With a small number of interval buttons and an up/down strum bar, embodiments can play almost any melody and more notes than a piano. One embodiment is directed to an interval-based guitar including fret buttons whose input signals are used to calculate the interval by which to change the pitch of the prior note. Providing input via a strum bar or a sensor, a new note is generated by adding or subtracting the interval to/from the prior note to generate a new note.

The user interface is designed to produce, when a zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . in a region 101, 102, . . . is activated, a musical tone-producing command in accordance with the activated zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . and region 101, 102, . . . , and the musical tone-producing command comprises at least one basic chord note command of a pitch that is contained in the basic chord associated with the activated region 101, 102, . . . and comprises a tune note command the pitch of which corresponds to the musical tone of the tune of the activated zone 111, 121, . . . ; 112, 122, . . . ; 11n, 12n, . . . . The invention also relates to a musical instrument, a method for producing combined sequences of chords and tunes, and a computer-readable storage medium.

The invention discloses a western and national ensemble instrument which comprises an instrument body, and a key assembly, a matrix circuit, a main board, a function control device and a timbre control device arranged on the instrument body; the key assembly is electrically connected with the matrix circuit; the matrix circuit is electrically connected with the main board; the main board is electrically connected with the function control device; the main board comprises an electrically connected timbre device packaged with a plurality of western musical instrument timbres and a plurality of national opera timbres. Due to the fact that the timbre control device is arranged on the panel of the instrument body, the timbre control device is electrically connected with the function control device by the main board to invoke timbre information corresponding control and any matching and superposition control.

Handpull musical instrument comprising housing parts for treble and bass connected by a bellows (1), associated sound and/or signal producing equipment and mechanical parts, and comprising a treble keyboard (4) installed in the treble housing (2) and a bass keyboard (5) installed in the bass housing (3), wherein the treble housing (2) is configured as an columnar hollow body (6) in angular design, which is open on the bellows side and opposite thereto comprises an opening (7) for receiving a treble cover (8), wherein the treble cover (8) is arranged so as to be aligned at an acute angle to an instrument central plane (M) between the two housing parts (2, 3), such that the treble housing (2) is tapered towards the instrument front face (V) and, thereby, the treble cover (8) is displaced towards the front and the treble cover (8) forms the treble keyboard (4).

An accordion includes a right hand play side, a left hand play side, a bellow provided between the right hand play side and the left hand play side. A plurality of columns of buttons provide on at least one of the right hand play side and the left hand play side. Each of the plurality of columns may have at least three buttons to which three single pitches are assigned, the three single pitches constituting a triad major chord. Embodiments of the present invention provide a user-friendly system for accordionists that can also cover more than 90% of the accordion songs being public in the world.
