Urban Lawnmowing with Scythe

I recently picked up a scythe outfit from Scythe Supply to tackle my yard when the height of the grass gets above what my reel mower can handle. Totally new to the instrument. I have a small urban lawn with a funky shape, some areas are narrower than the snath is long. Some areas are bounded by foundation on one side. In the wide-open spaces I feel I've got decent feel for the correct motion. In the narrow spaces I'm unsure what the best motion is. Do you just narrow the arc of the swath equally from the left and from the right? Some other motion? I'd love to hear the tips you have!

With the caveat that I have yet to mow a smooth lawn...
I find when working around trees and in small spaces, forgetting the correct core motion and just using your arms helps. I try to keep the blade low and in parallel with the ground, and if I angle the movement just a little toward me, I can cut in smaller spaces. If the blade is sharp, it usually works.
Best of luck!
