A method and system for analyzing patterns in the relationships of notes of an input piece of music. The method comprises generating a set of the most frequently occurring note pitches in ascending pitch order that matches an interval pattern, and detecting out-of-key pitches that lie outside of this internal pattern. One or more potential key sequence bifurcations are identified which represent a list of possible key sequences according to forwards and backwards analysis. By finding patterns of repetition in the chordal sequences that may be generated according to these key sequence bifurcations, a key sequence that allows the most frequently recurring chord sequences may be chosen. Chord sequences may be analyzed by using ghost chords, temporary harmonic structures that are created, updated and finalized over time according to a combination of essential and inessential note fragments. The method further comprises identifying non-harmony pitches according to the analyzed chord sequence.

An audio signal generation device (20) includes: an acquirer (210) configured to acquire biological information of a human subject; an audio signal generator (245) configured to generate an audio signal based on at least one of a plurality of pieces of sound information; and a switching cycle decider (241) configured to decide a switching cycle, such that first sound information switches to second sound information at a cycle that is in accordance with the biological information, the first sound information and the second sound information being included in the plurality of sound information pieces, and the audio signal generator (245) generates an audio signal based on the second sound information, at the switching cycle decided by the switching cycle decider (241).

A chord judging apparatus for judging chords of a musical piece, is provided with a processor and a memory for storing data of the musical piece, wherein the processor specifies plural segments in the data of the musical piece, estimates a tonality of each of the specified segments based on component tones included in the segment, and judges a chord of the plural segments of the musical piece based on modulation in tonality, when modulation is introduced in the estimated tonalities of the plural segments.

Systems and methods herein utilize psychoacoustic principles to process audio signals to achieve a desired result. In some embodiments, an exemplary process utilizes a combination of re-harmonization and auditory processing techniques in which a plurality of filtered audio cues are sampled, created and down-mixed into a final music file output, which may be designed to trigger specific effects on the function of the body and the brain. In some embodiments, enhanced audio material may be altered during the stream or fixed for a desired result at the beginning of the stream. In some embodiments, a signal enhancement process may be embedded into silicon or a media player, decoder or device with software. In other embodiments, audio or video material may be encoded or finalized into the media file.

The present invention relates to an overlay for a touchscreen piano keyboard implemented on an iPad or similar touchscreen device. It includes a screen covering sheet, that has a top surface pitted with hollows, such that it blocks activation of the touchscreen piano keys when lightly pressed, but not when more firmly pressed, thereby emulating the pressing of physical piano keys.

An electronic music instrument comprises an input configured for receiving at least one note event from an input device having a plurality of input elements configured for generating at least one note event when activated; a software module configured for including: at least one instrument plugin configured for defining sounding note events and non-sounding control events, and at least one play assistant module, wherein the software module is further configured for at least one of the group comprising excluding the control events from being processed by play assistant functions and excluding play assistant functions generating control events.

The present invention provides touch sensor means for detecting the touch location along the length of an outfitted piano key as it is pressed, so as to then offset the notes of an associated piano keyboard accordingly during play. When such an outfitted key is pressed in combination with other piano keys, the touch location along the length of the outfitted key, and the separation intervals and timing of the key presses, are analyzed to determine the intended chord, such that before any notes are sounded, the notes of the pressed keys are configured for the sounding of that chord. This arrangement enables playing a wide range of notes using just a few keys, so as to provide a substantially reduced-size keyboard with full-sized keys sufficient for real-time playing. This arrangement also enables configuring the note offsets of those pressed keys to conform to a selected musical key, so as to simplify the layout of the keyboard by eliminating its black keys, while still supporting the playing of non-conforming notes. This arrangement further enables applying pitch variation to those note offsets in order to emulate the string stretching, whammy bar, and fretless neck playing techniques for guitars and basses. This arrangement even further enables playing advanced chords in a simplified manner. Finally, this arrangement enables providing a wide assortment of keyboards that can differ in the type, number, size, and functionality of their outfitted keys.
