General information
El Cieguito de Nagua, the stage name of González Alvarado Pereyra (also known as Bartolo Alvarado), was one of the greatest and most influential accordionists and singers of Dominican merengue típico. Born blind on January 10, 1947, and passing away on March 27, 2020, his prodigious musical ear, incredible speed on the accordion, and authentic style made him an undisputed legend of his country's folklore, serving as an inspiration for multiple generations of musicians within the genre.

Origins and early development
He was born in the rural area of La Jagüita, belonging to the municipality of Cabrera, in the province of María Trinidad Sánchez. Born without the sense of sight into a humble family of ten siblings, his parents encouraged him from a very early age to find refuge in music. He first learned to play the tambora and later the harmonica in a traveling magic show. At the age of nine, he picked up the accordion for the first time, demonstrating an astonishing talent that led him that same year to perform on the famous radio program Buscando estrellas on the station La Voz Dominicana. After that experience, he returned to his region and began playing at local parties and weddings alongside his father, where people affectionately nicknamed him el cieguito.

Musical career
His professional career took off in the mid-1960s when entrepreneur Fabio Inoa heard him perform and proposed recording his first tracks on a single record. Those initial pieces were Yo seré tu mayoral and Marita, which marked the beginning of his commercial impact. Starting in the 1970s, he consolidated a massive musical catalog that transcended the Dominican Republic and reached the diaspora living in the United States with great force, where he traveled regularly to hold massive performances.

Among his most memorable and reproduced hits are El diente de oro, La luz, La aspirina, Dame mi pato Gabino, and Sabor a caña. In addition to his radio singles, he left landmark albums such as La Aspirina (1975), Ay Si Si (1978), and Aprovéchate (1991), performing constantly in dance halls, popular clubs, and television shows over several decades.

Musical style and cultural impact
The style of El Cieguito de Nagua was defined by rescuing the pure essence of merengue de línea oaxaqueña or perico ripiao, while injecting it with a unique interpretive grace, characterized by clear, confident singing and extremely fast, clean accordion arrangements. His musical proposal achieved a perfect balance between maintaining the traditions of the Dominican countryside and adapting the typical sound to the demands of urban dance halls. His work served as an indispensable cultural bridge to dignify and popularize accordion music across social sectors in major cities, proving that visual impairment did not diminish his mastery or technical virtuosity.

Legacy
El Cieguito de Nagua is considered one of the foundational pillars in the history of merengue típico. He spent his final years residing in the United States due to ongoing medical treatments for kidney issues. At the age of 73, he passed away at a medical center in Brooklyn, New York, due to respiratory complications. His physical departure caused a period of national mourning within the Dominican artistic sphere. Today, his legacy remains alive through monuments erected in his honor, the constant playing of his classics during Dominican festivities, and the deep reverence held for him by new accordionists who mimic his unmistakable way of playing.
