The mandocello is a plucked string instrument of the mandolin family. It is larger than the mandolin, and is the baritone/bass instrument of the mandolin family. Its eight strings are in four paired courses, with the strings in each course tuned in unison. Overall tuning of the courses is in fifths like a mandolin, but beginning on bass C (C2). It can be described as being to the mandolin what the cello is to the violin.

Paddy Bush plays the mandocello on the song Kashka From Baghdad.
