Source-derived summary

William Richard Cumpiano (born April 30, 1945) is a builder of stringed musical instruments and is known for his writing and teaching of the art of luthiery. He has been involved in the preservation and understanding of the fading musical and musical craft traditions of his native Puerto Rico. Cumpiano was instrumental in the development of the first feature-length documentary about the cuatro and its music, Our Cuatro: The Puerto Ricans and Stringed Instruments, Volumes 1 and 2.

Early years

Cumpiano was born into a middle-class family in San Juan, Puerto Rico. His father was a native of the town of Rincón, Puerto Rico, and his mother from Boston, Massachusetts. He was raised in the capital of Puerto Rico where he received his primary and secondary education. On one occasion, Cumpiano wandered into an eatery next to his grade school which had a jukebox. He listened to Odilio González sing a décima with a guitar and a cuatro in the background. In Puerto Rico the type of music that Odilio González sang is known as "música jíbara", which is Puerto Rico's cultural equivalent of what in the United States is called country music. This early experience would eventually grow into his passion for Puerto Rican traditional instruments and singing.

The linked authority record independently contributes the date 1945-04-30. The account is most persuasive where William, Cumpiano and Puerto can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as puerto Rican master guitarmaker. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 17, 2026. The linked authority identifier is Q8017204. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1945.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
