A chord information extraction device includes a character group extractor, a determiner and a corrector. The character group extractor extracts a character group corresponding to chord information from score image data representing a music score. The determiner determines whether the character group extracted by the character group extractor follows a predetermined chord notation rule. In a case where the character group extracted by the character group extractor does not follow the chord notation rule, the corrector corrects the extracted character group to follow the chord notation rule.

A method, apparatus, and User Interface, and product for assisting users learning to play the Chords of any selected Song quickly and easily and provide a Means to quickly and easily generate the individual Note sounds for the Chords of the selected Song employing a broad range of Virtual and Physical Instrument.

A harmony generation device and a program for the same which can generate a natural harmony sound are provided. The harmony generation device (1) generates first and second harmony tones to which a voice input through a microphone (M) is shifted in pitch by first and second shift amounts calculated based on both the voice input through the microphone (M) and a chord determined from performance information of an electric guitar (G) input through an input device (34). That is, since the first and second harmony tones can be tones based on the chord of the electric guitar (G) that changes from moment to moment, the harmony sound obtained by mixing the first and second harmony tones with the voice input through the microphone (M) can be a natural harmony sound that is rich in variation according to the chord of the electric guitar (G).

Coordinated audio and video filter pairs are applied to enhance artistic and emotional content of audiovisual performances. Such filter pairs, when applied in audio and video processing pipelines of an audiovisual application hosted on a portable computing device (such as a mobile phone or media player, a computing pad or tablet, a game controller or a personal digital assistant or book reader) can allow user selection of effects that enhance both audio and video coordinated therewith. Coordinated audio and video are captured, filtered and rendered at the portable computing device using camera and microphone interfaces, using digital signal processing software executable on a processor and using storage, speaker and display devices of, or interoperable with, the device. By providing audiovisual capture and personalization on an intimate handheld device, social interactions and postings of a type made popular by modern social networking platforms can now be extended to audiovisual content.

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 method of generating a musical score file for one or more target musical instruments with a score generation component based on input audio data. The score generation component finds candidate musical notes within the input audio data using a frequency analysis to identify segments that share substantially the same audio frequency, and finds a best match for those candidate musical notes in audio data associated with target musical instruments in a sound database. A generated musical score file can be printed as sheet music or audibly played back over speakers.

A platter based electronic musical instrument is operable to shift the frequency of a sound sample as a function of a rotational position of the platter and a scale selection signal. The electronic musical instrument is further operable to render the frequency shifted sound sample. A scale of the electronic musical instrument is selected via a leash. The leash determines the selected scale of the electronic musical instrument as a function of input provided by (e.g., a chord played on) a controlling musical instrument.

A chord estimation apparatus estimates a first chord from an audio signal, and estimates a second chord by inputting the estimated first chord to a trained model that has learned a chord modification tendency.

A method and apparatus for music generation may include steps of receiving any length of input; recognizing pitches and rhythm of the input; generating a first segment of a full music; generating segments other than the first segment to complete the full music; generating connecting notes, chords and beats of the segments of the full music and handling anacrusis; and generating instrument accompaniment for the full music, and comprise a music generating system to realize the steps of music generation.

Provided is an electrophonic chordophone system (20) comprising sensor (24) configured to be operatively responsive to respective strings of a guitar (22). The system (20) also includes non-transitory processor-readable storage means (26) which contains first and second user-configurable tonal formats (28) and (30). Also included is processor (32), arranged in signal communication with the sensor (24) and storage means (26), and adapted to associate a melody group of notes producible by the strings with the first tonal format (28) in a one-to-one mapping or direct correlation, and to associate a control group of notes producible by the strings with the second tonal format (30) in a one-to-many mapping or indirect correlation. Also included is a synthesiser (34), arranged in signal communication with the processor (32), and configured to produce both the first and second tonal formats simultaneously in substantial real-time. The first tonal format (28) is actuatable via the melody group of notes and the second tonal format (30) is dynamically selectable via the control group of notes and also actuatable via the melody group of notes. In this manner, a melody is producible via the first tonal format (28) with a dynamic backing track producible via the second tonal format (30), all using one guitar (22).
