A method of providing repetitive motion therapy comprising providing access to audio content; selecting audio content for delivery to a patient; performing an analysis on the selected audio content, the analysis identifying audio features of the selected audio content, and extracting rhythmic and structural features of the selected audio content; performing an entrainment suitability analysis on the selected audio content; generating entrainment assistance cue(s) to the selected audio content, the assistance cue(s) including a sound added to the audio content; applying the assistance cues to the audio content simultaneously with playing the selected audio content; evaluating a therapeutic effect on the patient, wherein the selected audio content continues to play when a therapeutic threshold is detected, and a second audio content is selected for delivery to the patient when a therapeutic threshold is not detected.

A method for transferring data between a storage and playback device and a server containing at least one audio file having information for producing a tempo that is sensible to at least one user as the at least one user performs a repetitive motion activity, the storage and playback device being capable of storing and playing the information in the audio file, the method comprising, at the data storage and playback device, or at a combination of the server and the data storage and playback device: receiving a request to substantially match at least one audio file based on its beats per minute for outputting on the storage and payback device; identifying a metadata tempo tag for each designated audio file, each tempo tag indicating the tempo of the audio file; and causing to be delivered to, or providing to, the storage and playback device the audio file.

A control method includes receiving a detection result relating to a first event in a performance; changing a following degree in a middle of the performance to which a second event in the performance follows the first event; and determining an operating mode of the second event based on the following degree.

A method for producing and streaming music generated from biofeedback. The method employs machine-readable language instructions that alter received signals from a wearable biofeedback device, generating musical tones to be played on a portable electronic device and/or shared with others. The varying musical tones that are produced by the method can be modulated by the user to reach a targeted state of emotion.

Systems, methods and apparatus directed to a global metronome configured at each of one or more locations to receive a high accuracy timing signal and responsively update a local clock thereto, to determine a phase of a virtual metronome using the updated local clock, a predetermined epoch start time and a predetermined virtual metronome period, to phase synchronize a local metronome to the virtual metronome, and to control local devices providing audio playback and/or a sequence of nonmusical events in accordance with start/stop/tempo messages configured in accordance with the local metronome. By using the global metronome at each of a plurality of locations to synchronize/control devices at those locations, the local devices that each of the plurality of locations are inherently synchronized with each other.

By allowing the movement of a user to affect the playback of content, the entertainment characteristic or uplifting spirits derived from content playback itself can be enhanced. The timing at which the user places his/her foot on the ground while walking or the timing at which the user shakes or changes from swinging in one direction to swinging to another direction is detected. Then, content, such as a music piece or moving pictures, is played back by allowing the timing of beats or bars of the music piece or the timing of scene changes or cut changes of the moving pictures to be synchronized with the timing of the movement of the user.

A device for generating a real time music accompaniment includes a music input interface, a music mode classifier that classifies pieces of music received at the music input interface into one of different music modes including at least a solo mode, a bass mode, and a harmony mode, a music storage, and a music output interface. A music selector selects one or more recorded pieces of music as real time music accompaniment to an actually played piece of music received at the music input interface, wherein the one or more selected pieces of music are selected to be in a different music mode than the actually played piece of music. A music output interface outputs the selected pieces of music.

A music data processing method includes estimating a performance position within a musical piece, and updating a tempo designated by music data representing a performance content of the musical piece such that a tempo trajectory corresponds to a transition in a degree of dispersion of a performance tempo, which is generated as a result of estimating the performance position with respect to a plurality of performances of the musical piece, and the transition in the degree of dispersion of a reference tempo. The performance tempo is preferentially reflected in a portion of the musical piece in which the degree of dispersion of the performance tempo falls below the degree of dispersion of the reference tempo, and the reference tempo is preferentially reflected in a portion of the musical piece in which the degree of dispersion of the performance tempo exceeds the degree of dispersion of the reference tempo.

Due to discrepancies in musical timing signatures, the invention assesses whether a recorded displacement, expressed in terms of beats and fractions, between exit and entry points for a potential musical splice or cut, corresponds to permit a seamless music splicing of different musical sections. Assessment is achieved by establishing a third time base of pulses having a length dependent upon a lowest common multiple of fractions within respective bars for different sections, with the bars of the respective sections then partitioned into an equal number of fixed length pulses. A coefficient aligns different time signatures; it is a ratio between pulses within the different sections. The coefficient identifies corresponding locations of a cut point, related to a suitable anacrusis, in terms of respectively an aligned bar, beat, quaver and fraction in differing time signatures. The coefficient ensures that the time anacrusis in one time signature is interchangeable with others.

A method for controlling a playback tempo of an audio track to be presented at an audio output, the audio track comprising a plurality of audio components, a first audio component of the plurality of audio components being associated with a plurality of sets of audio data, wherein each set of audio data in the plurality of sets of audio data is associated with a respective playback tempo range, the method comprising receiving a playback tempo for presenting the audio track at the audio output, selecting, from the plurality of sets of audio data, a set of audio data that has an associated playback tempo range comprising the received playback tempo, and allocating the selected set of audio data to the first audio component for presenting the audio track at the audio output.
