an early type of mandolin

The mandola (US and Canada) or tenor mandola (Europe, Ireland, and UK) is a fretted stringed musical instrument. The mandola has four double courses for a total of eight strings. The instrument is tuned in fifths, to the pitches of the viola (C-G-D-A low-to-high), a fifth lower than a mandolin; the courses are tuned in unison rather than in octaves.
