Regarding the band, I recommend Bandari and Mystery Garden. Bandari mainly emphasizes a kind of soft absoluteness, which is the purest and most calming music. Therefore, his works are quite good. I recommend some famous ones to you:
Wonderland, Silent Mountain Forest, Spring Field, Blue Sky, Misty Forest, Sunlight Coast, Garden of Dreams, Glazed Lake, Breeze Valley.
The Hill of the Rising Sun, followed by the Mystery Garden. His music is great and relatively sad, among which the most famous is song from a secret garden, Heartstrings, Adagio Adagio, The Rap Drum, Chaconne Chakong Dance, Cantoluna Moon Poetry. Ode To Simplicity is beauty
There is also a kind of light music that is more pleasant to listen to-novel music. I believe everyone has heard of "I had a cold in that corner", and this is a novel music. The source of his creation is to let readers read novels better, so his melody is very gentle. Here are some songs: Classicriver (this one is said to remind people of the feeling of first love). Sorry I'm late, please.
