Violone

The term violone (Italian pronunciation: [vi.oˈloːne, vjo-]; literally 'large viol', -one being the augmentative suffix) can refer to several distinct large, bowed musical instruments which belong to either the viol or violin family. The violone is sometimes a fretted instrument, and may have six, five, four, or even only three strings. The violone is also not always a contrabass instrument. In modern parlance, one usually tries to clarify the 'type' of violone by adding a qualifier based on the tuning (such as "G violone" or "D violone") or on geography (such as "Viennese violone"), or by using other terms that have a more precise connotation (such as "bass violin", "violoncello", or "bass viol").
