Tuning problems under capo bar

[Mike and Jane Spalding]

Jonathan, Michael, and list,

In my "newbie's" practice, I see lots of pianos that haven't been tuned in several years or thousands of miles.  I carry a 4 oz. bottle of ProTek CLP and a small artist brush, with which I liberally wet the wire where it crosses the pressure bar, v-bar, and understring felt.  This dramatically improves rendering.
