Clavichord

Compass: C/E–a². Fretting starts at: e.

e-f-f#|g-g#-a|b♭-b-c¹-c#¹|d¹-e♭¹-e¹|f¹-f#¹-g¹-g#¹|a¹-b♭¹-b¹| thence uncertain.

Two bridges arranged at right angles to the case and two ‘hold-downs’ attached to the soundboard. Compartments with lids to left and right of the keyboard. The cranking of the keylevers is reminiscent of the Neapolitan clavichord in the Leipzig museum
