METHOD FOR CREATING MUSIC AUDIO SEQUENCES FOR MUSIC THERAPY Russian patent published in 2011 - IPC A61M21/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, psychology, and can be used in creating music audio sequences to be applied in restorative and preventive medicine. Musical compositions are sampled; parts creating binaural beat of healthy organs are inserted into fragments of the musical compositions. Then the musical compositions are listened to choose those lasting for 20 minutes and able to cause positive reactions in listeners. The chosen musical compositions are analysed, included definition of note frequency description, arrangement of frequencies of used notes, their length and sound volume, spectral analysis of the chosen music parts that involves calculation of spectra, dynamics of spectra of note lengths, their averaged estimated spectral parametres and time dynamics. Fragments for 1-7 minutes are specified in the selected parts of the musical compositions by band signal demodulation involving specifying a number of frequency bands, determining the width of each frequency zone of the band and demodulating signals; it is followed with consonance analysis of the demodulation signals that involves determining a Fourier spectrum for each signal, specifying all paired components of a consonance spectrum and self-similarity frequencies, their averaged estimated characteristics in the whole set of frequencies within the range 30 Hz to 20 mHz, collectively estimating the averaged parametres found and selecting and rating the fragments of the selected parts of the musical compositions with amplitude modulation spectrum reaching its maximum. The rated fragments of the selected parts of the musical compositions are selected and classified by matched or proximate border parametres of their frequency bands to those of rhythms of human organs and systems within the frequency range 20 mHz to 20 kHz, and introduced in an electronic computer database. The fragments show quantitatively calculated criteria of sound similarity and consonance of various frequency components of modulation spectra.

EFFECT: method allows increasing clinical effectiveness of music therapy.
