i sort of understand this..

so how does it apply to autoharp..

i tune every string to concert pitch with electronic chromatic tuner..
[well as close within 5 cents either way
as i can get each string to stay in tune..]

but should the bass & treble strings be 'adjusted'
as in the case of piano explained above..

or is the slightly delinquent tuning of autoharp
accepted as part of its 'traditional' musical character..???
