The octobasse (or octobass in English) is an enormous string instrument built in 1850 by French instrument maker Jean-Baptiste Vuillaume that is capable of creating sound at a frequency of 16 Hz, which is lower than humans are capable of hearing. Curator Colin Pearson carefully demonstrates a playable replica tuned two octaves below a cello at the Musical Instrument Museum in Phoenix, Arizona.
Musicians took turns trying out their own versions of the theme from Jaws on the museum’s octobasse.
