In 1979, Fazioli started designing the first prototype for a baby grand piano. He was assisted by a small team consisting of Professor Pietro Righini, an expert in musical acoustics, and Professor Guglielmo Giordano, a wood technologist, as well as Virgilio Fazioli and Lino Tiveron. The prototype of the F183 model was completed in June 1980, followed at the end of the year by the prototypes of two other models, the F156 and the F278. In the latter half of the year, work began on the prototype of the F228 model.
