Orchestra
noun
Remember how you learned that 管弦楽 means "orchestral music?" Well the group that plays that music is an orchestra.
This is a jukugo word that uses the on'yomi readings of the kanji. You should be able to read this on your own. 楽 has two on'yomi readings, but you know it's がく here because it's about 音楽 (music)!
小さな管弦楽団でバイオリンを演奏しています。
I play violin in a small orchestra.
