This research discusses mood classification in pop and jazz music using Mel Frequency Cepstral Coefficients (MFCC) and the K-Nearest Neighbor (KNN) algorithm. The dataset used consists of900 songs with mood labels angry, happy, relaxed, and sad obtained from Kaggle. The data wasprocessed by extracting 13 MFCC features and then continuing with classification using KNN. The research results show that the best accuracy reaches 64% with K=9. Accuracy at K=7 obtained a value of 60%, while at K=11 an accuracy of 58% was obtained. Evaluation was carriedout using accuracy, precision, recall and f1-score metrics, with the best results found at K=9. Thisresearch emphasizes the importance of selecting K parameters for optimizing mood classificationmodels.
