What does your harp sound like if you simply tune it a semitone or tone flat?

Well, I wouldn’t try to go too low. I tried to re-string my Irish lap harp (22 string) from the low F to the C below middle C and was really disappointed. Strings were rubbery, way too low tension for my comfort, and the sound was just dull. Also, the thicker the string, the more stress on the soundboard, so you have to be careful about that. My best advice would be to consult the manufacturer for their advice before tweaking.

You could also try talking to Markwood Strings, Laurie might be able to do a string analysis and figure out what arrangement of strings would keep the tension while dropping the notes. Just down tuning the strings may not be the best plan, you harp is designed to have a certain amount of tension on it. Strings need to match the available vibrating length, the diameter of string that will produce that note desired while fitting the length and soundboard hole as well as provide the correct tension. It is a science.
