An electronic musical instrument includes a plurality of keys respectively specifying different pitches when operated; a memory; and a sound processor. In response to a current operation of a current key, which is one of the plurality of keys, the sound processor retrieves the information stored in the memory for a previous operation, if any, of a previous key, which is a same as the current key or is another one of the plurality of keys, and performs a prescribed processing on a beginning part of the waveform data generated for the current operation of the current key in accordance with the retrieved information stored in the memory for the previous operation of the previous key so as to generate processed waveform data in response to the current operation of the current key. The resulting processed waveform data can be configured to better mimic artists' performance of an original instrument.

This tone setter comprises a memory for storing a program and a plurality of tone data; and at least one processor configured to utilize the plurality of tone data and set a sound source. In accordance with the program, the at least one processor executes accepting a selection of one or more tones made by an operation of a user; and setting, in at least an electronic musical instrument or a sound source of the tone setter, tone data corresponding to the selected one or more tones such that sound having the selected one or more tones is generatable with the musical instrument.

A controller to control an electronic musical instrument includes: first to third input units for a user to input play data and a frame having the first to third input units arranged therein. The frame has a wall surrounding an internal space, the wall has a three dimensional surface, the first to third input units configure one set, and the first to third input units configuring one such set are arranged adjacent in a circumferential direction of the three dimensional surface and the plurality of sets are arranged adjacent in a longitudinal direction of the three dimensional surface.

A musical instrument with two or more classes of pitches where at least one class is a diminished chord extended over an arbitrary number of octaves, and another class is another chord extended over the same span of octaves. The pitches of the second class of pitches are interlaced with the pitches of the diminished chord of the first class of pitches. Additional classes are chords similarly interlaced with other classes, with one class of any interlaced pair of classes being a diminished chord.

A musical instrument performance solution is described. Labels with visual indicators provide a reference to performers such that a proper combination of instrument inputs may be selected at the appropriate time. The visual indicators include colors and/or shapes. The visual indicators may be presented using differently-colored lyrical text, where each color corresponds to a set of notes. Each set of notes may for a chordal group such as a triad. The visual indicators may be associated with labels that are able to be adhered to various instrument inputs such as keys of a keyboard or piano.
