Thinner is stronger than thicker, but the improvement is minimal for high carbon steel music wire. There's a discussion about this between me and Newton somewhere in the depths of the pianotech archives. >Should I try a thicker string that will withhold the tension, or a >thinner string for a higher pitch? Both strings will have the same stress for the same scale position, but the thinner string is stronger so more able to withstand that same stress level. I'd check for other factors that are causing the breakage. By the way, what is the pitch, speaking length, and wire gage of the offending string?
