Mona Butler has been a bassoonist in Pacific Northwest Ballet Orchestra since the orchestra was founded in 1989, and PNB's Music Librarian since the position was created in 1996. Marketing Assistant Maris Antolin sat down with Mona in late February to talk about what a Music Librarian does, the years-long process of putting together the orchestra parts for Alejandro Cerrudo's One Thousand Pieces, and the hard-working artists of PNB's orchestra.
