The case of this small clavichord is made of walnut and is devoid of ornament save for a rose of carved wood and parchment, and mouldings around the perimeters of the lid, the upper and lower edges of the case, and the soundboard. D. O. M is possibly a maker’s initials, but more likely an abbreviation of 'Deo optimo maximo' ('To the best and greatest God'). The instrument sits on a stand of walnut (of a later date). This small German instrument is a triple-fretted instrument. The compass is C/E to c’’’, with a short octave in the bass.
