Japanese Court Music
Gagaku
noun
It's so elegant and so comforting. This is Japanese court music, and it's what fancy court people listened to in Japan back in the day. You can also call it gagaku if you'd like.
This is a jukugo word that uses the on'yomi readings of the kanji. You should be able to read this on your own. Since this word's about music, 楽 uses its secondary reading がく (the one you learned with 音楽).
