A secondary consideration within movement and positioning of you and your equipment would be how you image the final playback form to take. Will this be in a simple, single-channeled situation where the objective needs to come across clearly? Or an omniscient setting, like listening with headphones, where the experience is described as ‘immersive’ and multi-layered? Monophonic recordings (one-channel) lend themselves better to more simple playback situations. On the other hand, binaural or stereo recordings have the capability to capture a 360-degree field detailing the textures of a specific moment, or environment.
Remember that some of the most simplistic sounds leave the listener open to interpretation. I find real complicated environments too deterministic. Simple noises can in the end, offer more complexity, leaving room for details to develop and evolve. "Pure" noises can be easily layered, worked and built upon in order to form a more accurate description of a mood or situation.
In the end however, it’s up to you to decide what’s important. The operative words being here: experimentation and quantity. Our ears are incredibly complicated, far more than any microphone. Only through direct knowledge of your equipment, the nature of its “voice” and the movement (or lack thereof) of your body in relation to it, can you begin to understand the dynamics of your recorded sonic environment.
