The linear speed will be greater the farther from the center the trombone player is, assuming the same angular velocity (i.e., speed measured in degrees per second). The center I referred to above was an apparent center of a line segment formed by the one-space projection of the circle on the (e.g.) y-axis, no point of which would correspond to any point on the circle closer to the center of the circle, of which they ain't none anyway being how as all points on a circle are equidistant from the center.

If you can't lure them with logic, baffle them with bullshit
