May I ask, what is the ringtone that is usually used in elementary schools when classes start and end?

Our bell is Clyde Mann's "Music Box Dancer" with a few tones slightly removed and then it is: Class time is here, please return to the classroom and get ready for class, of course there is also a preparatory bell before this; our bell is Clyde Mann's "For Alice" which is also slightly modified with a few tones and then it is: Time for class, teachers, you've worked hard!
