Angklung and Kolintang Libels or commonly called ANABEL, is one of the extracurricular activities in SMAN15 Surabaya. In my opinion, this extracurricular is very unique, because in modern times like this it is very rare for people who want to play traditional musical instruments

To attract students to join an extracurricular activities, anabel does not only bring folk songs. Anabel also performed songs that were hitz, said Fajrina as anabel member. Anabel practices every Saturday at 10:00 to 12:00, but if there is an event they practice every day. They were trained by Mr. Yono, if Mr. Yono did not come they practiced on their own.

Anabel has also participated in Angklung and Kolintang Competitions in East Java. In the competition, Anabel returned with 2 trophies. The first cup won first place in angklung competition, and second place in kolintang competition.
