The History of the Musical Saw

No one really knows the actual history and development
of the musical saw.  Some historians believe it may date
back to the 1700s though it didn't gain popularity until
the early 1900s.  The music saw, despite its early popu-
larity, is still a relatively unknown musical instrument
today.  In addition to sourcing the links I provided in my
presentation linked below, discover other sources on the
evolution of the musical saw and its early development.
