My friend plays the guitar, do you know much about guitars?
1_Wizard
Not much,  but I know a few things.  For example, I know the guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel string.

That's interesting, what exactly is a chordophone?
1_Wizard
A chordophone is a musical instrument that makes sound by way of a vibrating string stretched between two points.

That makes sense, do you know when the guitar was invented?
1_Wizard
Not exactly, but the modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance and the five-course baroque guitar.

Wow it sounds like it has quite the history, what exactly is a gittern?

A guittern was a small gut instrument that first appears in literature during 13th century in Western Europe.
