CLAVIERS BAROQUES -- Library of Stringing Schedules

Timothy McGee single 2 x 8' (more or less after Zuckermann ca 1960)


This instrument was originally strung in steel music wire with some brass in the bass. It has a two-piece bridge with a very long scaling in the treble and mid while the short bass section is considerable foreshortened. We were not able to bring soft iron to pitch in the treble and mid (to middle C) and so used steel there. We tried various diameters of twisted paired yellow brass, plain yellow brass and red brass in the bass and settled on red brass with some yellow to smooth the transition to against the soft iron. This schedule was produced by trial and error. We were quite pleased with the sound.

*strings, keys and jacks are traditionally counted from the left (lowest note), although stringing schedules traditionally list wire from the highest note to the lowest, probably because most builders string the treble first. It is confusing, I know; sorry.
