Music historians have long suspected that the inventors of the violin wanted to imitate the human voice, and a study out on Monday shows how 16th to 18th century luthiers in Italy did it. Researchers at National Taiwan University asked a professional violinist to play 15 antique instruments, including one from 1570 by Andrea Amati, the early 16th-century luthier from Cremony, Italy who is considered to be the father of the modern four-string violin.

Others played in the study were from the Stradivarius family, conceived by Antonio Stradivari, who improved upon Amati's design. First, researchers recorded scales played on the 15 antique instruments played by a professional violinist and recorded at Taiwan's Chimei Museum. Then, they recorded the voices of eight men and eight women, ranging in age from 16 to 30 years, who sang common English vowels.
