Methods for beat synchronization between media assets are described. In one embodiment, beat synchronized media mixes can be automatically created. By way of example, a beat synchronized event mix can be created by selecting a plurality of media assets, arranging the media assets into an unsynchronized media mix, determining the a profile of each of the media assets in the media mix, automatically beatmatching the beats of adjacent media assets in the media mix, and automatically beatmixing the beats of adjacent beatmatched media assets to create the beat-synchronized media mix. The media assets that can be used include both audio and video media. Media assets are selected based on a specific set of media asset selection criteria, which can include music speed or tempo, music genre, music intensity, media asset duration, user rating, and music mood. A beat synchronized event mix can be subdivided into one or more event mix segments. Each event mix segment can have its own selection criteria.

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.

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, 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.

The invention discloses a piano teaching method based on big data and neural network, which classifies the beats of audio files, uses the training BP neural network to classify and identify different piano music genres, and adopts Thayer's two-dimensional emotion model to convert the emotion of music The types are divided into four categories: happy, relaxed, sad and angry. The digital music files are stored in different storage layers, and the differences are added with identity information tags. The large cloud database will compare the differences in beats and timbres in each segment and The corresponding music file fragments in the large cloud database are fed back to the teaching terminal. According to the scores of piano practice results of different rhythms, genres, and emotions, combined with identity information of different regions, ages, and genders, similarity evaluations of different priority levels can be carried out according to identity information. The evaluation of teaching results is more targeted and can be based on user preferences. Music content, find the music content closest to it for practice recommendation.
