Here is one of the reasons I chose the brushed finish on my horn, as well as the sterling bell and the red/gold/yellow brass body. It can look so different in varying light. This is a screen capture from a video I just did. They only editing I did was to take out an orange "traffic" cone.
In case you are interested, here is the video. I'm playing a pretty song that I heard on "Matlock" called "Golden Slumbers Kiss Your Eyes". It is a good example of why we don't stop practicing after we know the notes. There are several connections between notes that I was not happy with. Perhaps when I was playing full-time such things would have come on the first attempt, but these days I need to practice to get them the way I want.
