I recommend Richard Clayderman's piano music, because Richard Clayderman's piano music makes people intoxicated, forget their troubles and fall asleep. For example, his autumn whispers, dream wedding, starry sky, memorial of love and so on. Followed by serenade, tearful, fascinating, but also conducive to sleep. For example, Schubert, Haydn, Mozart, Chopin and other musicians serenade.
