This video is (as most media works are) based on many multifaceted specuations surrounding Beethoven's life. However, there are many "theories" about the final days of his life, and this particular "theory" is clean, and excellent for children.
I distinctly remember watching it in the fourth grade, and being a classical soprano myself, finding I was absolutley enchanted with the entire idea. It sparked an interest in Beethoven's life, which, years later, lead to the reading of many a biography and viewing of "Immortal Beloved", a movie which immediatly became my favorite. Therefore, I would most definitely recommend this movie, (for children) it is succinct, clean, to the point, and for me, inspiring. Take it from one who viewed it as a child many a time, children will adore "Beethoven Lives Upstairs."
