the temple block and the sound from the sousaphone player -, could come together, which probably were not meant to meet (e. So for 16th notes, two sounds, - the sound produced where you stand e. A sixteenth note played at a tempo of 120 beats per minute, and the beat is set to be a quarter note, has a duration of 125 ms (60 s : 120 : 4). This would even be worse for a spectator in front of the group, lets say standing by the temple block: Since the sound from the sousaphone needs also 58 ms to go back to the beginning of the troop, the listener would hear the sound of the sousaphone 116 ms (2 * 58 ms) later than the sound of the drum set. Assuming the distance between the mobile drum set and the sousaphone is 20 meters, then the time difference is 20 m : 343 m/s = 0.058 seconds (distance divided by the speed of the sound). If the persons in the back of the troop (usually the sousaphone players) would synchronize with the sound of the mobile drum set, they would be late by the time the sound needs to travel to them. A larger Clique (group) has several members and therefore the whole troop can reach a length of 20 meters. The Tambour-major (drum major or conductor) leads the group followed by a row of temple blocks (similar to the wood block) and then the Gugge-drums (mobile drum sets), followed by marching bass drums (Timpani) followed by woodwind instruments (often Piccolo), then drummers and finally the brass instruments with the sousaphones usually at the end. Why is visual contact with the conductor important? Let me explain this with a group in a carnival parade.
