pro nobis" is for soprano, two violins, two cornetts, three trombones (one of which can be a viola da braccio) and basso continuo. Monteverdi also leaves the option to use trombones as part of the "sex instrumentis" of the Dixit Dominus and in the instrumental Ritornello a 5 between verses of Ave maris stella. From around 1617, when the maestro de' concerti at St. Marks changed to violinist Francesco Bonfante and correspondingly the ensemble changed from basically a brass ensemble to being more evenly mixed with brass, wind and string instruments. Monteverdi arrived at St. Mark's in 1613 and it is unsurprising that he includes trombones and strings for several more sacred works during his time here, published in his Selva morale e spirituale 1641. Of the c.40 items in this collection, six specify three or four trombones (or viola da braccio, ad lib): SV268 Beatus vir I, SV263 Dixit Dominus I, SV263 Dixit Dominus II, SV261 Et iterum venturus est, SV258 Gloria in excelsis Deo, SV281 Magnificat I. Each is for 3-8 voices with 3 violins (apart from SV261), the trombones/violas and basso continuo. Monteverdi also specified trombones in two more sacred works: SV198 Laetatus sum (i) (1650) for 6 voices, 2 violins, 2 trombones and bassoon and SV272 Laudate Dominum omnes gentes I (1641) for 5 voices 'concertato', 4 voice chorus ad lib, 4 viola da braccio or trombones and basso continuo. Germany/Austria A prolific composer for trombones in Germany in the 17th century was Heinrich Schütz. His Fili me, Absalon (SWV 269) and Attendite, popule meus (SWV 270), are both scored for bass voice, four trombones (of which two are optionally violins) and basso continuo, are well known. They are part of his first Symphoniae Sacrae collection dating from 1629 and commentators have noted that the style reflects his studies in Venice with Giovanni Gabrieli 1609–1612. Other pieces that specify trombones (according to Grove) are (grouped by the collection they were published in): Concert mit 11 Stimmen (1618): SWV 21, in Psalmen Davids (Psalms of David) Op. 2 (1619): SWV 38, 40–46, Symphoniae sacrae I Op.6 (1629): SWV 259, 269–271, 274, Symphoniae sacrae II Op.10 (1647): SWV 344, Symphoniae sacrae III Op. 12 (1650): SWV 398a, Historia (1664): SWV 435, 448, 449, 453, 461, 452, 466–470, 473, 474–476, Schwanengesang Psalm 119 (1671): SWV 500, although many others are suitable for trombones too.
