1613—Munich, Germany: At the wedding of Duke Wolfgang Wilhelm of Bavaria to Countess Magdalena of the Pfalz, the wedding party goes to the Frauenkirche, where, according to one report, “Throughout the church, high up, trombones, trumpets and kettledrums were heard” (Bowles, Music in Court Festivals of State).
