Franklin's new invention premiered in early 1762, played by Marianne Davies—a well known musician in London who learned to play Franklin's new invention. Initially Franklin named it the 'glassychord', but soon settled on 'armonica' as the name for his new invention—after the Italian word for harmony "armonia". Apparently Franklin built a second instrument for Ms. Davies, as she toured Europe with hers, while Franklin returned to Philadelphia with his own.
