A method for extracting the most representative segments of a musical composition, represented by an audio signal, according to which the audio signal is preprocessed by a set of preprocessors, each if which is adapted to identify a rhythmic pattern. The output of the preprocessors that provided the most periodic or rhythmical patterns in the musical composition selected and the musical composition is divided into bars with rhythmic patterns, while iteratively checking and scoring their quality and detecting a section that is a sequence of bars with score above a predetermined threshold. Checking and scoring is iteratively repeated until all sections are detected. Then similarity matrices between all bars that belong to the musical composition are constructed, based on MFCCs of the processed sound, chromograms and the rhythmic patterns. Then equivalent classes of similar sections are extracted along the musical composition. Substantial transitions between sections represented as blocks in the similarity matrices are collected and a representative segment is selected from each class with the highest number of sections.

The invention provides scoring a performance of a guitar part in a rhythm-action game. It operates in the context of a video game platform in communication with a display and a controller and involves receiving an input performance from the controller including at least one input chord note, each input chord note including an input string value corresponding to a struck string and an input fret value associated with the input string value. Then, a reference performance is provided, which includes at least two reference chord notes to be input at a target time, each reference chord note including a reference string value and a reference fret value associated with the reference string value. Then, a degree of matching is determined between the input performance and the reference performance, and a score is assigned to the input performance based on the degree of matching.

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.

A system and method for retrieving musical information from a database based on a melody fragment. The system may be used by a person without formal musical training to retrieve musical data (e.g., the name of a song, bibliographic information about a song, or the song itself) from a database by providing the melody or fragment of the melody of the desired music to a computer interface. The melody may be provided by singing, humming, whistling, or playing a musical instrument, for example, a keyboard. The inputted melodic information is encoded using relative changes in pitch and rhythm throughout the melody. The encoded information is then compared using a matching algorithm to similarly encoded melodic information representative of many musical pieces (e.g., songs). Results may also be sorted using a weighted algorithm.

A system and method for teaching music both visually and tactilely. In one embodiment, the invention comprises blocks shaped to resemble musical symbols used to compose music, including time signatures, notes, rests, and dots. Each of the blocks are relative in thickness such that for a given time signature, the correct rhythm for a given measure can be determined by laying one or more of the notes, rests and dots one over the other to see if their combined thickness is equal to that of a preselected time signature. The thickness of the block shaped to resemble the time signature is such that it only allows the correct number of blocks shaped as notes, rests or dots to be of equal thickness to thereby determine the correct rhythm. In addition, the correct rhythm can be determined by simply reading the shaped blocks as one would read music. The use of the shaped blocks having relative thicknesses allows a student to learn rhythm by trial and error and does not necessarily require that the student understand complex music theory. In addition, the blocks can be used by the student when clapping the correct rhythms. Other musical notation can be represented by blocks as well such as bar lines and slurs.

An apparatus for teaching rhythm includes a housing having a plurality of tempo indicator lights and a plurality of beat indicator lights corresponding to the tempo indicator lights, such that the beat indicator lights can be selectively illuminated to indicate a desired beat in a rhythm. Circuitry illuminates the tempo indicator lights in sequence and the selected beat indicator lights in sequence, so that a user may attempt to manually generate a sequence of sounds synchronous with the selectively illuminated beat indicator lights.

A computer implemented method for analysing sounds, such as audio tracks, and automatically classifying the sounds in a space in which arousal is one axis and valence is another axis. The location of a sound or track in that arousal-valence space is automatically determined using a computer implemented system that analyses, measures or infers values for each of the following base feature parameters: harmonicity, turbulence, rhythmicity, sharpness, volume and linear harmonic cost, or any combination of two or more of those parameters.

A user inputs, as a query pattern, a desired search-object rhythm pattern by operating a rhythm input device. At that time, a determination is made of a style of operation performed by a user on a rhythm input device, such as whether the user has operated a single key or a plurality of keys, or duration or intensity of the operation, and then, a user-intended performance part is identified, on the basis of the determined style of operation, from among one or more performance parts constituting a performance data set (automatic accompaniment data set). For the thus-identified performance part, a rhythm pattern search section searches an automatic accompaniment database for an automatic accompaniment data set including a rhythm pattern that matches the input rhythm pattern (query pattern).
