Hi, Jon. Well, it's interesting to me that you think ambient air and stage lights are significant (they are), but that heat from a laptop three inches from the strings isn't (I think it depends). This thread accidentally (my fault) jumped from CTuner (the CyberTuner list), but there's a post there from Tom Cole who thought that may explain what happened on his tuning this morning. He said, "It doesn't take much to make strings go flat as you point out. It might explain why the Steinway "L" I tuned this morning, whose lower tenor notes were in tune when I began (many freebies), had all gone flat after tuning to the top. I had to retune from about C4 down to B2 before tuning the bass. Now I wonder if the tenor went sharp after I left." This is exactly what I'm talking about. And it hasn't happened to me, that I've noticed, with my older, cooler but unhip laptop. I'm just wondering whether the newer, faster, hotter ones have crossed the line into being a heat problem. If you're saying that heating the strut is not significant, I would tend to agree. But direct convective or radiant heating of the strings, I'm thinking could be a problem. -Mark Schecter
