1. If you need to complete relatively heavy scientific assignments, it is recommended to choose some calm and relaxing music, such as classical music or light music. This type of music can help create a peaceful environment, reduce stress, and aid concentration.

2. If you like to listen to music while studying, you can choose some music with a bright rhythm but not too noisy, such as jazz or pop music. As long as the rhythm and melody of the music are not so intense as to distract, this type of music may stimulate enthusiasm for learning and improve learning efficiency.
