This instrument is strung with 6 gut strings that are tuned to (relative to Kontakt):
D1, G1, C2, E2, A2, and D3.
Viols are fretted like early guitars or lutes, using movable wrapped-around and tied-on gut frets. The portable nature of the tied-on frets permits the viol player to make adjustments to the tempering of the instrument. On this particular instrument, the frets only extend 7 semi-tones on each string.
