Is there any possibility that I can use musical instrument in the library?
There is in fact a possibility to play a instrument in library.
The music library has a playing room, that you can reserve for a hour at a time. In the room there's an acoustic and an electric piano. But you are free to bring your own instrument as well.
You can visit the music library at the 2nd floor of the old building at the main library, or call the music library's customer service number 02-262 0658 to make the reservation.
