Thanks, Deb. In the beginning, everything tended to go sharpish–now everything tends to go flattish. (The crazy weather is not helping–with the windows open so early–even though the harps and the piano are nowhere near them–their tone changes, I think.) I do have to tune daily so far. I think that will change as the harp settles in–my FH26 was the same in the beginning, but after a while it stayed in tune much, much longer. I will treat the FH36S bass strings with kid gloves–although I swear I was not being vigorous with them. I do understand from my reading that those phosphor-bronze cores just do not stretch.
