Guitars arose quietly as quality folk instruments in central Europe but were not given serious attention until the early 1800's. They are characterized by a softly waisted body with a fretted fingerboard. Most commonly there are six strings although there is a surprising range of stringings and tunings in the family. I have examples from three strings (the Mexican Tres) to fourteen strings (the Phillipine Octavina). Generally there are no sympathetic resonators strings in this family. They are larger than the mandolin family (mostly) and are intended to be held across the chest of a standing or seated player.
Here are also Examples of the family that I have worked on:
1903 Mail Order Guitar
The ArcAngioli Guitar
Small scale guitar
