Ayres Extemporae is a historically informed group based in Belgium and The Netherlands. It is formed by the Moldovan-Spanish violinist Xenia Gogu, the Spanish cellist Víctor García García, playing on a five-string cello piccolo, and the Portuguese cellist Teresa Madeira. Winners of the 2024 York International Young Artists Competition, they received, among other prizes, a professional recording contract from Linn Records for their debut album, scheduled for 2025. In 2022, they were awarded the 1st Prize and the Audience Prize at the Semana de Música Antigua de Estella-Lizarra, which led them to be programmed at the 2023 edition of the festival. In the same year, they also won the 2nd Prize at the Biagio Marini International Early Music Competition in Germany. They have performed at many international festivals, such as FIAS in Madrid, Schwetzinger Festspiele in Germany, Femàs in Sevilla, Festival À Corda in Portugal and FestiVita! - Early Music Festival in Brussels.

An innovative feature of their proposal is the experimentation in the realisation of the basso continuo, inspired by recent research on the use of bowed string instruments in the basso continuo in Corelli's time. The combination of a four-string cello and a five-string piccolo cello brings new textures to the traditional instrumentation of cello and harpsichord. Through ex temporae improvisation of countermelodies, ornamentation, and chordal realization, they aim to enhance the diverse affects in music and search for a variety of textures and colours, also achieved by the changes in the roles of each instrument.
