| Summary: | In order to deal with the great challenge of the arrival of information society to the traditional music teaching concept and practice, an overview of the teaching ability structure of music normal students supported by information technology is put forward. The changes in the structure of teaching ability caused by information technology are analyzed, that is, to analyze the cultivation of teaching ability of music normal students by integrating music subject knowledge with information technology platform and promoting relevant elements in combination with teaching activities. By using Fitzgerald and our proposed long+short method to separate Beach Boys songs at the singing music ratio of-6, 0, and +6 dB, the singing signal (left column) and music signal (right column) are relative to the average values of SDR (first row), SIR (second row), and SAR (third row) of pure singing and pure music. Experiments show the effectiveness of this method. © 2022 Hao Cheng et al.
