The present application relates to the technical field of music
information management, in particular to a
flute national style music
library construction method and
system, comprising the following steps: acquiring
flute music audio data, dividing paragraphs according to time axis, extracting
timbre waveform change track, accumulating and counting
timbre turning point, intercepting melody main line information, identifying scale ascending and descending and continuous change, defining path node, labeling melody structure, comparing
timbre fluctuation section, recording style change position, and generating style music
library field combination. In the present application, the audio data of the
flute music is carefully divided and the timbre waveform change is counted, the key timbre change in the music is captured, the node is divided through the directionality of the scale trend, not only the multi-dimensional
visualization of the information is increased, but also the structural characteristics of the melody are more clear, the national style sample music is called to compare the structure, and the consistent style segment is counted, which greatly improves the convenience and efficiency of the user to search and identify the specific style music.
