摘要： PROBLEM TO BE SOLVED: To provide an improvisation assist system of an electronic keyboard instrument that even a player having little music knowledge or experience can realize advanced pseudo performance expressions with simple key touch operations. SOLUTION: In this system, when operating a plurality of keys in a keyboard 5K having a plurality of white keys and black keys at the same time (M1), a key touch pattern corresponding to a distribution state of the operated white key/black key is determined out of a plurality of key touch patterns P1-P16 to be predetermined based on plural input tones Nip due to the simultaneous operations of the plurality of keys (M3b), and a type corresponding to the judged key touch patterns P1-P6 is decided out of a plurality of types of harmonization functions (M3c). Then, the plurality of input tones Nip are converted into a desired chord Nop by executing the harmonization function instructed by the decided type (M3d). In the harmonization, a function for producing a plurality of kinds of voicing including tones except chord tones is prepared in addition to a chord tone producing function.

摘要： Mask generation section (30) generates an evaluating mask, indicative of a degree of dissonance with a target sound per each frequency along a frequency axis, by setting, for each of a plurality of peaks in spectra of the target sound, a dissonance function indicative of relationship between a frequency difference from the peak and a degree of dissonance with a component of the peak. Index calculation section (60) collates spectra of an evaluated sound with the evaluating mask to thereby calculate a consonance index value indicative of a degree of consonance or dissonance between the target sound and the evaluated sound.

摘要： PROBLEM TO BE SOLVED: To provide a method of manipulating a complex waveform by considering the harmonic and partial frequencies as moving targets over time in both amplitude and frequency and adjusting the moving targets by moving modifiers in both amplitude and frequency.SOLUTION: The manipulation of harmonic frequencies and the synthesis of harmonic frequencies are based on the harmonic rank. The modifiers move with the movement of the frequencies based on rank. Harmonic transformation modifies, by rank, the waveform from one source to a waveform of a second or target source. Harmonics and other partials accentuation identifies each of the frequencies and its relationship to adjacent frequencies as well as fixed or moving thresholds and make the appropriate adjustment. Interpolation is also disclosed as well as models which imitate natural harmonics.

摘要： PROBLEM TO BE SOLVED: To precisely evaluate a degree of consonance or dissonance between a plurality of sounds. SOLUTION: A mask generation section 30 generates an evaluating mask M indicating, per each frequency, a degree of dissonance between a target sound VA and a sound at the frequency by setting a dissonance function Fd indicating relationship between a frequency difference from a peak p and a degree of dissonance with a component of the peak, for each of a plurality of peaks p in a spectral sequence RA of the target sound VA. An index calculation section 60 collates a spectral sequence RB of an evaluated sound VB with the evaluating mask M to calculate a consonance index value D indicating a degree of consonance or dissonance between the target sound VA and the evaluated sound VB.
