Why was the viola created?

The viola was created in the early 16th century as part of the evolution of string instruments to fill a harmonic and tonal gap between the violin and the cello. It offered a richer, darker sound that allowed for deeper harmonic textures in ensembles and orchestras. Its size and tuning (C-G-D-A) enabled it to play both melody and harmony, making it a versatile instrument in various musical styles. Over time, the viola became integral to chamber music and orchestral compositions, contributing to the overall richness of the string family.
