1. If you want to make a mobile phone ringtone, it should have an uplifting melody, right?

Maksim's "Croatian Fantasia" is quite suitable, as is "Youth".

2. If it is relatively quiet and soothing

"Orange Temperature", "Schindler's List" and "Night's Piano Music Series Five" (Night's piano music series are all good, you Listen to them all)

3. Sad Lyrical Category

"You left Nanjing, and no one talked to me from now on" (Classic! Unsurpassed!)

Pianoboy’s piano music is also good, especially lt;annabellegt;

These are all piano music, which I think are unique and not likely to be repeated with other people’s ringtones.

My cell phone ringtone is "Countless Times" by Aoyama Dema, it's loud enough!
