Final answer:
Church councils and documents have addressed concerns about sacred music throughout history. Examples include the Annus qui council and the Second Vatican Council. Concerns shared include the need for reverence and the preservation of traditional forms. Two examples of music that address these concerns are 'Ave Maria' by Schubert and 'Miserere' by Allegri.
Step-by-step explanation:
Throughout history, church councils and documents have addressed the issues and concerns surrounding sacred music. One example is the council known as Annus qui, which took place in 1937. This council emphasized the importance of maintaining the solemnity and reverence of sacred music and discouraged the use of secular influences. Another significant event was the Second Vatican Council in the 1960s, which led to the publication of the document called 'Musicam Sacram.' This document provided guidelines for the liturgical music of the Catholic Church, encouraging the use of traditional and Gregorian chant.
One concern shared by these councils and documents is the need to maintain the sacredness and reverence of music in religious contexts. They highlight the importance of music serving as a means of worship and prayer, rather than simply for entertainment or secular purposes. Another concern is the preservation of traditional and sacred music forms, such as Gregorian chant, which have deep historical and cultural significance.
Two examples of musical pieces from different historical periods that address these concerns are 'Ave Maria' by Franz Schubert and 'Miserere' by Gregorio Allegri. 'Ave Maria' is a sacred song that reflects the traditional and devotional aspects of religious music, while 'Miserere' is a composition that showcases the solemn and reverential qualities of sacred music.
