Embodiments of the present invention provide methods, computer program products, and systems to for automatic key transposition. Embodiments of the present invention can be used to determine compatibility between a known melody capable of being generated by a pitch generation system and a first performance profile associated with a first performer that performs in conjunction with the pitch generation system. Embodiments of the present invention can be further used to determine an appropriate key to update one or more pitches associated with the known melody, to be generated by the pitch generation system during the performance by the first performer, based on the compatibility between the first performance profile and the known melody.

The present disclosure relates to a scale shifting and volume adjustment method, apparatus and device, the method comprising obtaining air pressure difference; selecting a scale to be played corresponding to the air pressure difference according to a preset scale selection strategy; obtaining a volume value corresponding to the air pressure difference according to a preset volume acquisition strategy; adjusting the volume of the notes of the scale based on the volume value. The present disclosure is capable of automatically shifting scale according to the air pressure difference, and adjusting the volume in a convenient and hassle-free manner.

Techniques are disclosed herein for generating harmonious audio. An input for changing a mode of an electronic device from a first mode to a second mode can be received and, in response, a controller of the electronic device can modify electrical connections between a matrix circuit and a set of keys of the electronic device. In modifying the electrical connections, a set of tones associated with a first subset of keys of the set of keys can be associated with a second subset of keys of the set of keys. Keys of the second subset of keys can be adjacent to at least one other key of the second subset of keys and tones of the set of tones can be associated with respective keys of the second subset of keys. Audio output when one key is operated can be harmonious with audio output when other keys are operated.

A method for generating voice identifications for MIDI (Musical Instrument Digital Interface) note signals. The method provides voice identification for every note in MIDI signals, which makes music learning intuitive and easier. The method can be used with any MIDI instruments as a separate unit, or a part of such instruments. Solfege is used as voice identification system since it is widely used in music education. However, any such system can be used or newly devised by preparing a different set of patches.

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.

In a synthesizer 1, the highest note number is set from the allowed Oct width and the lowest note number of a sound production part in a setting table 11e, and if the note number of an Arp note memory 12b is not between the lowest note number and the highest note number, the note number of one octave unit is added to or subtracted from the note number of the Arp note memory 12b. Consequently, the note number of the Arp note memory 12b is corrected to the pitch range between the lowest note number and the highest note number, and thus can be corrected to the sound production pitch range of the timbre of the sound production part, and arpeggios can be outputted using sounds that are more appropriate for an instrument of said timbre.

Claviation is a rapid and intuitive method for transposing an electronic musical keyboard in real timefast enough to support key changes during play using the keys themselves. The player enters transposition mode via a pedal or button and presses two keys in sequence to define the transposition interval. These two presses are muted to avoid disrupting the music. This three-step action is as efficient as a musical triplet, easily fitting within a beat and becoming faster with practice. Crucially, claviation requires no calculation, naming, or conceptualizing of intervals. It enables the player to keep scales primarily on the white keys, even through key changes, eliminating the need to learn key signatures and multiple fingerings. A piece learned in one key is effectively learned in all. Claviation accelerates learning, enhances improvisation, and preserves spatial patterns across key changes, making the keyboard easier to learn, understand, and compose music on.
