Work
Gallus represented the Counter-Reformation in Bohemia, mixing the polyphonic style of the High Renaissance Franco-Flemish School with the style of the Venetian School. His output was both sacred and secular, and hugely prolific: over 500 works have been attributed to him. Some are for large forces, with multiple choirs of up to 24 independent parts.
His most notable work is the six part Opus musicum, 1577, a collection of 374 motets that would eventually cover the liturgical needs of the entire ecclesiastical year. The motets were printed in Prague printing house Jiří Nigrin, which also published 16 of his 20 extant masses. The motet O magnum mysterium comes from the first volume (printed in 1586) which covers the period from the first Sunday of Advent to the Septuagesima. This motet for 8 voices shows evidence of influence by the Venetian polychoral style, with its use of the coro spezzato technique.
His wide-ranging, eclectic style blended archaism and modernity. He rarely used the cantus firmus technique, preferring the then-new Venetian polychoral manner, yet he was equally conversant with earlier imitative techniques. Some of his chromatic transitions foreshadowed the breakup of modality; his five-voice motet Mirabile mysterium contains chromaticism worthy of Carlo Gesualdo. He enjoyed word painting in the style of the madrigal, yet he could write the simple Ecce quomodo moritur justus later used by George Frideric Handel in his funeral anthem The Ways of Zion Do Mourn.
His secular output, about 100 short pieces, was published in the collections Harmoniae morales (Prague 1589 and 1590) and Moralia (Nuremberg 1596). Some of these works were madrigals in Latin, an unusual language for the form (most madrigals were in Italian); others were songs in German, and others were compositions in Latin." />
