Quaternaglia Guitar Quartet (QGQ) is acclaimed as one of the world’s top guitar ensembles. Composed of Brazilian guitarists Chrystian Dozza, Fabio Ramazzina, Thiago Abdalla, and Sidney Molina, QGQ is recognized for its artistic excellence and for its significant contributions to the expansion of guitar quartet repertoire. Over the past twenty-five years, the group has established a wide canon of original pieces and ambitious arrangements through collaboration with composers like Leo Brouwer, Almeida Prado, Egberto Gismonti, Sergio Molina, and Paulo Bellinati.

The quartet first attracted the attention of international criticism when it was awarded the “Ensemble Prize” at the Havana International Guitar Contest in 1998. Since then, the group has regularly performed in various notable guitar and chamber series in the United States and the world. Following the group’s California debut, the Los Angeles Times wrote: “an aura of purity pervaded the concert of the Brazilian guitar quartet…[it] met all the requirements with equanimity and intelligence.”

Quaternaglia’s discography includes the albums Quaternaglia (1995), Antique (1996) – for which the group received the “Carlos Gomes Prize”– Forrobodó (2000), Presença (2004), Estampas (2010), Jequibau (2012) – nominated for “Prêmio da Música Brasileira” – Xangô (2015), as well as Quaternaglia (2006), a DVD recorded live.

The quartet has performed in fifteen American states including Arizona, California, Illinois, Ohio, New York, Mississippi, and Texas, in countries like Portugal, Spain, Australia, Cuba, Uruguay, and Argentina, and in seventeen Brazilian states. Quaternaglia has also conducted Master Classes and lectures at various institutions including Yale University, the Jacobs School of Music (Indiana University at Bloomington), and the Coimbra Conservatory.

For Quaternaglia, the second decade of the 21st century began with a tour of six Brazilian states followed by orchestra appearances under Isaac Karabtchevsky and Leo Brouwer at Sala São Paulo, Theatro da Paz (Belém), and Teatro Nacional de Cuba.

Besides recording twenty-five original Brazilian pieces among the nearly fifty dedicated to the quartet, Quaternaglia is especially well-known for its interpretations of Villa-Lobos and Leo Brouwer, as well as for renditions of Renaissance and Spanish music.

Based in São Paulo, Brazil, the musicians of Quaternaglia Guitar Quartet use four custom-made guitars by renowned Brazilian guitar maker Sergio Abreu.

“Quaternaglia’s newest album [Xangô] is a winner. It has great playing, beautiful and unhackneyed music, and excellent recording quality. The group is certainly among the elite of the guitar quartets […] Quaternaglia is a state-of-art-ensemble; they are melodically and rhythmically vital, virtuosic and exciting, individually beautiful in sound, and capable of enchanting sonorities. The performances are preternaturally exact in their synchronization while still sounding spontaneous. A first-rate disc. Al Kunze (Soundboard, USA)


“Playing a programme made up of compositions written by their fellow countrymen, the Brazilian guitar quartet Quaternaglia are on top form here on this, their latest CD release [Jequibau].

The music is excellent, without any fillers-in and it is a programme, which can be listened to over and over without any drop of interest.” Steve Marsh (Classical Guitar, England)
