How was viols tuned?

Answer 1

Viols were typically tuned in fifths, similar to modern string instruments, but their specific tuning often varied by type. The most common tuning for the treble viol was C-G-D-A, while the bass viol was tuned similarly, but an octave lower. Viols could also be tuned in different ways for specific musical contexts or personal preferences, sometimes using alternative tunings like C-G-D-A for the tenor viol. The use of frets allowed players to adjust their finger placement for various tunings.
