Default Autoharp scale length/string tension

How much tension is on autoharp strings? I heard they are similar to piano wires. What's the scale length of an autoharp. How high can I tune the thinnest autoharp string?

Strings are TIGHT and fairly heavy. My highest note is a D (don't know the number, but I'd say above the staff). An autoharp will have 1500-2000 lbs of tension on the frame. Nothing like a guitar's.

There is no "scale length" for autoharp, that's why the strings are all at a different lengths. If you're looking to build one you should look at the established design such as represented in the Oscar Schmidt design. I believe there are good construction plans available.

String gauges, pitch, tension, and sounding lengths were worked out long ago to produce an instrument with good volume and tone at a total tension that the robust construction will tolerate. Altering those parameters risks structural damage, so tread lightly.

Thanks. I did not at that time. I wonder what the different lengths are.

It depends on the exact model and manufacturer of the autoharp. The vibrating length generally ranges from 7-1/2" to 19-1/2".

Once again, a trip down Memory Lane from 2014 - in your own words:

None of us leads a charmed life: 1500-2000 pounds of sudden explosive force will put you in the hospital (or worse) - and you already got away lucky at least once...

Some friendly advice : If you haven't done so already, please seek professional assistance ASAP: if you have and your present therapist isn't helping you get to where you want/need to be, find someone who can (and will) - before matters result in permanent injury or fatality...
