Moderato is an instrumental background sond in the anime xxxHolic.
Moderato is similar to the song Lost Heart. It is sad yet peaceful and is played at similar times. Moderato appears to be a bit more happy than sad in feeling whereas Lost Heart is more sad than happy. For example, Lost Heart will play when Watanuki befriends a spirit and the spirit is being exorcised and Moderato will play after the spirit is gone, when Watanuki is thinking about the spirit and how it's in a better place now. thumb|300px|right
