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.
Mozart did not use a piccolo in any of his symphonies, but used it in his German Dances, K. 104 and in the Overture to The Abduction from the Seraglio. Beethoven was the first composer to use the piccolo in his symphonic works. He wrote separate parts for it in the finales of his Fifth, Six and Ninth symphonies.
