The viola, a fifth below the violin
The viola shares the three lower strings of the violin and adds a fourth, lower one, a fifth below. Its sound is warmer and darker; viola music is mostly written in alto clef.
As on the violin, use the fine tuners for small adjustments and the pegs for larger ones.
