The method of using the sound of music to tell time is as follows:
1. Open the music player on your phone or computer, select a favorite music as the time ringtone, and add it to ringtone list.
2. In the alarm clock settings of your phone or computer, choose to use a custom ringtone to set the time alarm, and set the ringtone to the music you just added.
3. Set the alarm time and repetition period, and save the settings.
4. When the alarm time arrives, the phone or computer will play the set music time ringtone.
