I believe it was RT who proposed the following tuning to Alina for
her new tekerő, but can't be sure as the mail trail was somewhat
convoluted:
Do you have a piano? If so you can use that to get you in the ball
park.
Just tune the melody string ( that is the one that has all the keys
tuching it ) to D, just about middle C.
Then tune the string that has the buzzing bridge on it ( that would
be the one closest to your body ) to the same D.
This tuning has the disadvantage that it would put the tension on the
strings off (unless Alina’s instrument is set up for this tuning and
I don’t know it). Standard tekerő tuning is to have the melody
string on the E above middle C, the buzzing bridge tuned to the A
below middle C and the bass drone to the A an octave lower. While
tuning the melody string to D won't cause a problem, tuning the
drones up a fourth as RT suggests could create problems, depending on
the strings.
