A 'tunesmith' is one so nicknamed because the individual or persons craft (compose) a tune from scratch.
When the location of Broadway called Tin Pan Street remained in its prime time, every music publisher's office would have sounds originating from the various cubicles of males and ladies pursuing the next success.
Sheet music was the primary source of songwriter's royalties throughout those days, and to please the public with a song predestined to be a popular piece was a lofty goal.
It's then only fitting that the lettering influenced by a 1920s-era piece of sheet music for a song called "Jerry" would be named Tunesmith JNL.
