In music and music theory, the beat is the basic unit of time, the pulse (regularly repeating event), of the mensural level (or beat level). The beat is often defined as the rhythm listeners would tap their toes to when listening to a piece of music, or the numbers a musician counts while performing, though in practice this may be technically incorrect (often the first multiple level). In popular use, beat can refer to a variety of related concepts, including pulse, tempo, meter, specific rhythms, and groove.

Method and apparatus for distributing haptic synchronous signals
InactiveCN101896962AElectrophonic musical instrumentsSynchronisation arrangementDistribution systemTactile device
A haptic signal distribution system capable of distributing haptic synchronous signals includes a master haptic device and groups of slave haptic devices. In one embodiment, the master haptic device is configured to distribute haptic synchronous signals to slave haptic devices. The haptic synchronous signals, for instance, may include information relating to a tempo for a piece of music. A haptic signal distribution system, for example, allows a master wearable haptic device to selectively distribute haptic synchronous signals to one or more groups of slave wearable haptic devices via a wireless communications network. Upon receipt of the haptic synchronous signals, each slave wearable haptic device generates a series of haptic feedback having a rhythm of beats in response to the haptic synchronous signals.

Musical instrument for easy accompaniment
InactiveUS7161080B1Preclude musical mistakesImprove playbackElectrophonic musical instrumentsComputer scienceSpeech sound
This electronic musical instrument has an extremely simple user-interface that can be played with only three fingers, one at a time. A user selects from among a small set of chords, and chooses a music-ending. This enables novices to extemporaneously produce good, simple rhythm-guitar and rhythm-banjo music to accompany singing. Strummed-guitar, finger-picked guitar, and finger-picked banjo music is composed by replaying pre-recorded elemental chording-phrases and music-ending phrases. The chording selectors also provide limited notes between strummed chords for embellishment. Optional music-endings automatically match the selected voice, key, beat, tempo and volume, nearly precluding musical errors. Common musical keys and chord types are provided to accommodate all voice ranges, and the majority of songs common to the western world. Persons capable of singing on tune can play this instrument after a brief familiarization without any practice, playing guide, or prior musical education.

Beat matching for portable audio
ActiveUS20090178542A1Avoid harmonic jumpsMinimize changesGearworksMusical toysComputer scienceAudio frequency
Beat matching for two audio streams extracts beats from each, computes a conversion ratio from one stream to the other stream by an initial beat alignment plus a stability-maintaining beat alignment. A variable resampling converter or time scale modifier adjusts one stream to align beats with those of the other (reference) stream. Thus for cross-fading two music streams the beats of the fading-in stream can be matched to those of the fading-out stream for a seamless transition.

Method and apparatus for pacing human body exercises using audible cues
A method and apparatus for pacing human exercises includes a sequence of pre-recorded, repetitive humanly perceptible signals in which a first, accented signal pulse, such as the first beat in a four-four measure of musical time, establishes a repetitive rhythmic tempo to thus provide timing track signal for synchronizing various phases of an exercise. The rhythmic pulses, which are preferably provided by a percussion instrument such as a drum and accompanied by musical tones, are accompanied by instructions verbalized by an exercise trainer in synchronization with the timing track signal. The perceptible signals are preferably audible and are optionally accompanied by or replaced by visibly perceptible signals such as flashing lights.

Real-time jamming assistance for groups of musicians
Real-time jamming is automatically assisted for musicians. A real-time audio signal is received of played music that is played by at least one person. Beat is tracked of the played music from the real-time audio signal and accordingly a time of a next beat is predicted. At least one of chords; notes; and drum sounds is recognized from the real-time audio signal and repetitions in the played music are accordingly detected. A next development is predicted in the played music, based on the detected repetitions, including at least one of chords; notes; and drum sounds that will be played next, and respective timing based on the predicted time of the next beat. A real-time output is produced based on the predicted next development in the played music.

Systems, apparatuses, and methods for performing adaptive audio mixing are disclosed. A trained neural network dynamically selects and mixes pre-recorded, human-composed music stems that are composed as mutually compatible sets. Stem and track selection, volume mixing, filtering, dynamic compression, acoustical / reverberant characteristics, segues, tempo, beat-matching and crossfading parameters generated by the neural network are inferred from the game scene characteristics and other dynamically changing factors. The trained neural network selects an artist's pre-recorded stems and mixes the stems in real-time in unique ways to dynamically adjust and modify background music based on factors such as game scenario, the unique storyline of the player, scene elements, the player's profile, interest, and performance, adjustments made to game controls (e.g., music volume), number of viewers, received comments, player's popularity, player's native language, player's presence, and / or other factors. The trained neural network creates unique music that dynamically varies according to real-time circumstances.

Systems, devices, and methods for encoding digital representations of musical compositions are described. Various components of a musical composition that are defined in modern music theory, such as notes and bars, are encoded as respective hierarchically-dependent data objects in a data file. The hierarchically-dependent data objects encode the musical composition in a tree-like data structure with modular nodes and adjustable relationships between nodes. Note start times and beat start times are encoded independently of one another and characterized by a timing relationship that captures the expressiveness imbued when notes and beats are not precisely synchronized. Musical variations that preserve the timing relationship between the notes and beats of the original composition are also generated and encoded.
