I very much appreciate that EMS offers such a range of diameters for red brass music wire; I hadn't used brass strings for my many string instruments until I found EMS, the spools have a generous amount of wire on them and they're pretty affordable for the amount you get. This has allowed me to experiment, and I love the warmth and the bell-like tone of brass strings, a nice change of pace from steel strings. Learning to wind the loops on them has been challenging as the brass is softer than iron or steel but that has only impelled me to master a new skill.
