The first part of this paper examines the classification of traditional music culture and the method of integrating it with modern vocal teaching. Then, the association rule algorithm was used to establish the calculation model of integrating college vocal teaching and traditional music culture, and the weighted MINWAL algorithm improved the model. Finally, the degree of integration and the effect of integration between college vocal music teaching and traditional music culture were analyzed using indicators of integration degree, value, and acceptance. The fusion levels of singing style, voice, tune melody, lyrics, performance technique and dynamics were 4, 3.5, 4.3, 4.4, 4.1 and 3.9, respectively. The fusion level regarding teaching content was 4.1, and the fusion level in terms of practical activities was 4.0. A teaching strategy that is feasible and effective and has promotion value is the combination of college vocal music teaching and traditional music culture.
