Biber: Rosenkrantz Sonaten

Baroque violin refers both to the instrument in its Baroque setup and to the repertory and performance practice for violin from roughly 1600–1750. Typical instruments use gut strings, a lighter bass bar, a shorter/shallower neck angle, and no chin- or shoulder-rest. They are paired with a Baroque bow, whose camber and weight distribution encourage speech‑like articulation, sprung strokes, and a clear attack/decay. Pitch is commonly at A≈415 Hz (varying by region), and temperaments may be circulating or meantone rather than modern equal temperament. Stylistically, Baroque violin playing emphasizes rhetorical phrasing (the "Doctrine of Affections"), ornamental vibrato (used as a coloristic embellishment rather than a constant), extempore ornamentation, and expressive bowing. The music lives in sonatas (da chiesa/da camera), dance suites, concerti (including the concerto grosso), and theatrical or sacred contexts, nearly always underpinned by basso continuo.

Bohemian Baroque refers to Baroque-era music cultivated in the historical lands of Bohemia and Moravia (today the Czech Republic). It flourished in courts, cathedral chapels, Jesuit colleges, and pilgrimage churches during the 17th and early 18th centuries. Stylistically, it blends Italianate concertato writing and the stylus phantasticus with the contrapuntal rigor of Central Europe. It emphasizes basso continuo, expressive rhetoric, chromatic inflection, and brilliant writing for strings and natural trumpets, while also preserving a rich vernacular hymn tradition (kancionál) in Czech. The repertoire spans masses, litanies, motets, sonatas, sacred cantatas, and devotional songs, ranging from monumental polychoral works to intimate pieces for voice and continuo. Its sound world is at once ceremonial and devotional, often marked by festive trumpets for feast days and poignant chromaticism in penitential movements.
