Indian tambura also known as tanpura, or tambora is a long-necked plucked lute (a stringed instrument found in different forms
and in many places). The body shape of the tambura somewhat resembles that of the sitar, but it has no frets – only
the open strings are played to accompany other musicians. It has four or five (rarely six) wire strings, which are plucked
one after another in a regular pattern to create a harmonic resonance on the basic note (bourdon or drone function).
Tamburas come in different sizes and pitches: larger "males", smaller "females" for vocalists, and a yet smaller version is
used for accompanying sitar or sarod, called tamburi or tanpuri.
