If our eyes only saw frames (IE: 30 images a second), like a single lens reflex camera, we'd see images pop in and out of existance and that would really be annoying and not as advantagous to us in our three dimensional space and bodies.
In the Vienna of the second half of the 18th century, in addition to Haydn and Mozart, three symphonic composers, namely Leopold Hoffmann, Carl Ditters von Dittersdorf and J.B. Vanhal helped further the development of the symphony.
Â· just now. A symphony orchestra is a BIG band, ranging anywhere from 60 to 150 players, depending on what composition they are playing. A symphony can range from 40 minutes ( works by Joseph Haydn and Wolfgang Mozart) to over an hour and a half ( Gustav Mahler and Anton Bruckner). Other pieces, also played by a symphony orchestra, but not necessarily symphonies, can also last from a few minutes up to an hour.
