Mandola

The mandola (US and Canada) or tenor mandola (Ireland, and UK) is a fretted, stringed musical instrument. It is to the mandolin what the viola is to the violin: the four double courses of strings tuned in fifths to the same pitches as the viola (C-G-D-A low-to-high), a fifth lower than a mandolin. However, the mandola, although now rarer, is the ancestor of the mandolin, the name of which means simply "little mandola".
