摘要： PROBLEM TO BE SOLVED: To provide a musical composition retrieval system which can easily grasp the tendency of musical composition data stored in a musical composition database only by referring to the display of musical composition map obtained by mapping the musical composition data, and also provide a musical composition retrieval method thereof. SOLUTION: A musical composition map, being a self-organized map, is composed of a plurality of neurons including characteristic vectors comprising data corresponding to a plurality of evaluation items representing the characteristics of musical composition data and in which the neurons have tendencies from one end to the other on preliminarily fixed index evaluation items in the evaluation items mentioned above. To any of the neurons of the musical composition map, the musical composition data are mapped, and the status of the musical composition map is displayed according to a point corresponding to each of the neurons of the musical composition map. The musical composition map receives learning about the index evaluation items with a value, which gradually decreases from one end to the other, as an initial value. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： There is disclosed an analyser (101) for building a transcription model (112; 500) using a training database (111) of music. The analyser (101) decomposes the training music (111) into sound events (201a-e) and, in one embodiment, allocates the sound events to leaf nodes (504a-h) of a tree (500). There is also disclosed a transcriber (102) for transcribing music (121) into a transcript (113). The transcript (113) is sequence of symbols that represents the music (121), where each symbol is associated with a sound event in the music (121) being transcribed. In one embodiment, the transcriber (102) associates each of the sound events (201a-e) in the music (121) with a leaf node (504a-h) of a tree (500); in this embodiment the transcript (113) is a list of the leaf nodes (504a-h). The transcript (113) preserves information regarding the sequence of the sound events (201a-e) in the music (121) being transcribed.

摘要： An improved control structure for music synthesis is provided in which: 1) the sound generation provided to the adaptive function mapper (501) allows for a greatly increased degree of control over the sound produced; and 2) training of the adaptive function mapper (501) is performed using an error measure, or error norm, that greatly facilitates learning while ensuring perceptual identity of the produced sound with the training example. In one embodiment, sound data is produced by applying to an adaptive function mapper (501) control parameters including: at least one parameter selected from the set of time and timbre space coordinates; and one parameter from the set of pitch, delta pitch, articulation and dynamic. Mapping is performed from the control parameters to synthesis parameters to be applied to a sound synthesizer. In another embodiment, an adaptive function mapper (501) is trained to produce, in accordance with the information stored in a mapping store (503), synthesis parameters to be applied to a sound synthesizer, by steps including: analyzing sounds to produce sound parameters describing the sounds; further analyzing the sound parameters to produce control parameters; applying the control parameters to the adaptive function mapper (501), the adaptive function mapper (501) in response producing trial synthesis parameters comparable to the sound parameters; deriving from the sound parameters and the trail synthesis parameters an error measure in accordance with a perceptual error norm in which they are weighted in approximate degree to which they are perceived by the human ear; and adapting the information in the mapping store (503) with the error measure.

摘要： In an electronic musical apparatus having an acoustic instrument manually operable to commence an acoustic vibration and a tone generator responsive to the acoustic vibration to generate a musical tone having a pitch corresponding to that of the acoustic vibration, a pitch detecting device utilizes a pickup (3) for picking up the acoustic vibration to convert the same into a waveform signal. Further, a first detector (13) operates according to a fast algorithm for processing the waveform signal so as to responsively produce a first output representative of the pitch of the acoustic vibration, and a second detector (12) operates in parallel to the first detector (13) for processing the same waveform signal according to a slow algorithm so as to stably produce a second output representative of the pitch of the acoustic vibration. A selector (17) selectively feeds one of the first output and the second output to the tone generator so that the first detector (13) and the second detector (12) can cooperate complementarily with each other to ensure responsive and stable detection of the pitch of the acoustic vibration. An additional detector (15) processes the waveform signal to measure a time interval between a pair of the peaks so as to detect a plucking point. A controller (21) controls the tone generator according to the detected plucking point to change the timbre of the tone generator in response to the plucking point.
