    摘要： The present invention relates to an information processing device, an information processing method, and a recording medium for analyzing chord progressions more accurately. A featuring quantity extraction unit 41 extracts respectively a probability of given chords appearing simultaneously, a probability of transition from a given chord to another chord, if the given chord appeared, and a probability of transition of a given chord originating from another chord, if the given chord appeared, from chord progressions of musical compositions by analyzing waveforms of said musical compositions. A chord similarity calculation unit 42 calculates the similarities between the chord progressions of musical compositions and the user-input chord progressions based on those extracted these possibilities. A musical composition retrieving unit 43 retrieves musical composition chord progressions similar to the user-input chord progression based on the calculated similarities. The present invention is applicable to the information processing apparatus.

    摘要： In an automatic player piano, hammer sensors (26) monitor associated hammers (2) so as to report current positions on the hammer trajectories, and a data processor (27) analyzes the hammer motion for producing pieces of music data representative of the performance on the acoustic piano (100); the aged deterioration is influential in the relative position between the hammers (2) and the hammer sensors (26) so that the data processor (27) rectifies the relative position, the data processor (27) determines the turning point at which the hammer (2) changes the direction of motion, and compares the current value indicating the turning point with the previous value; if the difference is found, the data processor (27) adds a value of deflection of strings (4) to the current value so as to determine and memorizes the true value of the turning point; the data processor (27) analyzes the hammer motion on the basis of the true value so that the music data are reliable.

    摘要： A musical composition data creation device and method. An input audio signal indicating a musical composition is converted into a frequency signal indicating a frequency component size at a predetermined time interval. A frequency component corresponding to each sound of the equally tempered scale is extracted from the frequency signal at a predetermined time interval. Two accords, each consisting of three frequency components whose level sum is large among the frequency components corresponding to the respective sounds extracted are detected as a first and a second accord candidate. Each string of the first and the second accord candidate detected is subjected to smoothing processing so as to generate musical composition data.

    摘要： An automatic playing system (300) creates a feedback control loop (302) for the keys (1a, 1b) incorporated in an acoustic piano; key sensors (7), which are provided under the front portions of the keys (1a, 1b), informs a motion controller (11) of current positions (yx), and the motion controller (11) periodically compares the current position (yx) and a current velocity (yv) with a target position (rx) on a reference trajectory and a target velocity (rv) to see whether or not a positional deviation (ex) and a velocity deviation (ev) occur; when the motion controller (11) finds the deviations (ex, ev), the motion controller (11) multiplies the deviations (ex, ev) by a position gain (kx) and a velocity gain (kv) for determining an increment or decrement of the duty ratio of driving signals (ui), and supplies the driving signals (ui) to the solenoid-operated actuators (6) so as to accelerate or decelerate the keys (1a, 1b); the gain (kx) is variable depending upon the key motion so that the actual key trajectory becomes close to the reference trajectory.
