The two oval spinets built by Cristofori survive today. Ottavini are small spinets or virginals at four-foot pitch. It centers on Louis Rosen, a small businessman whose company produces spinets and electronic organs. The vibrato was a simpler circuit than on other consoles and spinets. Cristofori built the two oval spinets for the Medici family of Florence. Especially remarkable was the fact that the spinets started around US$500. Most spinets are smaller than regular harpsichords. This included an organ, three types of spinets, a violin, and another bowed string instrument. This compass is very common in spinets made between 1690 and 1710. The collections include harpsichords, virginals, spinets, organs, fortepianos, harps, lutes, citterns and guitars. The two spinets, though similar in design, are very different in their current state. Cristofori's oval spinets have two choirs of strings, each at 8-foot (normal) pitch. Thus spinets normally had a slightly different tone quality, with fewer higher harmonics. Spinets also had smaller soundboards than regular harpsichords, and normally had a weaker sound.
