Double Bass

[cachalot]

I can speak for the cello, the most important aspect to this is to anticipate the change in direction with the wrist; it has to start before the bow actually changes direction. The more the bow accelerates/decelerates, the more the bow change is noticeable

I’ve been trying to play long continuous drones with the bow, but it’s tricky to eliminate the sound of changing bowing direction. Does anyone have any suggestions on how to do that?

Lots of practice, learning to get the bow speed as slow as possible first and then, as @cachalot notes, the actual bow change is performed by the wrist. It’s a classic exercise to optimize for speed/pressure/sounding point. A meditation.
