Duo GlossArte stands for historically informed performance practice that brings early Baroque, Classical, and Romantic music to life as a coherent musical narrative. Our artistic core is the art of ornamentation—glosas—as musical speech: precise, stylistically authentic, and immediately present in the space.

„This new sound world will surely give pleasure“, „Great flair… solidly stylish and intelligent“  Lindsay Kemp (Gramophone), 23.03.2026

"Lively tempos... Ornaments in the style of the time... Sparkling enthusiasm."
Prof. Klaus Trapp (Klassik heute), December 27, 2025

"The unmistakably delicate sound of the silver trombone ... takes us on a journey around the Mediterranean ..." Rhein-Main Magazine, December 17, 2025

„Der kombinierte Klang aus dem silbrigen Ton der Posaune und dem vollmundigen Timbre der Orgel … warme und exquisite Klangfülle …“ Adrian Quanjer, 30.11.2025

The trombonist's virtuosity was astonishing, and the clear tone and varied program were thrilling. The captivating stage presence and relaxed yet focused performance rounded off the positive overall impression of this ensemble.

Duo GlossArte wurde 2019 vom Posaunisten Juan González Martínez und der Cembalistin/Organistin Lea Suter gegründet. Die Kombination aus historischer Posaune und historischen Tasteninstrumenten ist in der heutigen Konzertpraxis selten – nicht aus Mangel an Repertoire, sondern weil sie spezifische Kompetenz verlangt: Kenntnis von Quellen, Artikulation, Atemführung und Raumakustik, sowie ein gemeinsames Verständnis von musikalischer Rhetorik.

This is precisely where our work comes in: we combine research with stage practice and translate historical knowledge into a clear auditory effect. It is never about "museum," but about sound decisions that the audience can immediately understand:
How is tension created? Why does a line have a different effect the second time around? How can you recognize style without having read specialist literature?

„GlossArte“ ist Programm:
glosas (span. Verzierung) + arte (ital. Kunst).
Ornamentik verstehen wir als musikalische Grammatik. Sie entscheidet über Richtung, Gewicht und Affekt – und macht den Unterschied zwischen „richtig“ und „überzeugend“.

In our programs, you will hear ornamentation not as decoration, but as form: diminutions, cadences, trills, appoggiaturas, and rhetorical pauses are derived from sources and stylistic context and become a living narrative in the moment of the concert.

Early Baroque (ca. 1550–1650): Virtuosity and Affect. Italian and Iberian Centers, Stylus Fantasticus, Improvisation Practice, and Diminution.

Classical music (18th century): transparency , proportion, conversational character. Solo concerts and chamber music—in duos and in collaboration with ensembles/orchestras.

Romanticism (19th century to early 20th century):Sound architecture and space. Historically informed decisions on instruments, pitch, articulation, and registration practice—especially in dialogue with historical organs.

An auditory journey around the Mediterranean in 1600: brilliant timbres, rhetorical gestures, bold diminutions. The silvery trombone meets the warmth of the organ and the transparency of the harpsichord—festive and intimate at the same time.

Concert music of the 18th century: alto trombone and 16-foot harpsichord in a soloist profile, supplemented by strings when space and context allow. The program is flexibly scalable (soloist/orchestral instrumentation) and is suitable for church and hall acoustics.

Fin de siècle as sound: duo literature, opera paraphrases, marches, and character pieces—with a historical perspective on instruments and playing style. In expanded formats, also with trombone quartet on original instruments from the 1920s.

Repertoire and first recordings in the context of the historic Sauer organ (1928) and a historic Franz Kuhn trombone (1920). A program that brings sound history to life: technology, space, and musical expression intertwine.

Trombone & Organ (MDG, 2022): First recordings of Romantic music for organ and trombone, recorded with the Franz Kuhn Trombone Quartet on original historical instruments in the Die Glocke concert hall in Bremen.
Mediterranean Melodies (MDG, release date January 23, 2026): Virtuoso sonatas and canzonas from around the Mediterranean around 1600, recorded on silver trombones and claviorganum (harpsichord & organ).
