The keyboard compass of the original was C-e3 (51 notes). I have modified this in several ways. Firstly, I increased the overall width and length of the instrument to accommodate more bass and treble strings. This gives me a chromatic range of BB-e3 (54 notes) using an Italian size keyboard (octave span of 6.25"). A different way to modified the range for certain players is by using a French size keyboard (octave span of 6.125") giving a range of AA-e3 (55 notes) less one flat in either the bass or the treble. Both ranges allow the use of a transposer block for both low pitch and high pitch.

Standard Materials & Finish
Being a false inner-outer instrument, there is only one case. The case frame is made of poplar with a walnut wrestplank and pine bottom boards and internal frames. The natural keyboard touchplates and arcades are made of boxwood and the accidentals are walnut with holly skunk-tails. All of the false inner structure is of cypress and the soundboard is in European spruce. The jacks are of European beech with holly tongues. Box guides are cut from European beech.

The cases and lids are painted in a two-tone colorway and decorated in a variety of Italian motifs to suit the player's tastes. The stands are typically Italian with three turned legs supported on carved bases.
