Woodsy Drone

This is a tambura, an Indian fretless drone lute.

Wikipedia sez:

A tambura (South India) or tanpura (North India) is a long-necked Indian plucked string instrument. In its bodily shape it somewhat resembles the sitar, but it has no frets, as only the open strings are played as a harmonic accompaniment to the 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).
