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. The scale length of the mandola is typically around 16.5 inches (420mm). The mandola is typically played with a
plectrum (pick).
