 Music, both sacral and secular, kept developing during the Baroque period. High quality church pipe organs were built in churches from the 17th century; a fine specimen has been preserved in Leżajsk. Sigismund III supported an internationally renowned ensemble of sixty musicians. Working with that orchestra were Adam Jarzębski and his contemporary Marcin Mielczewski, chief composers of the courts of Sigismund III and Władysław IV. Jan Aleksander Gorczyn, a royal secretary, published in 1647 a popular music tutorial for beginners.
