text: It was at the beginning of the 19th century that orchestras got large enough for a conductor to be necessary - the main reason is that in a large orchestra, the time taken for the sound to travel from the front of the orchestra to the back is long enough for there to be a lag between what the violins and the timpani are playing (timps in the wrong place will bring everything to a halt).
