Based in Brooklyn New York, Samuel Zygmuntowicz has been crafting stringed instruments for about 30 years, working with musical greats such as Yo Yo Ma and Joshua Bell.
Many consider Zygmuntowicz preeminent in his field, as he works to construct violas, violins, and cellos with decades-old wood.
He has extensively studied the art of violinmaking and looks to the Italian makers of the 17th and 18th century like Antonio Stradivari for guidance.
But he also increasingly uses modern tools like CT scans and 3D laser vibration scans to hone his craft.
Zygmuntowicz spoke with NewsHour Weekend about the evolution of his craft and what he looks for when piecing together a new instrument. View the video above.
