Scrabble?! RAVALE

Definitions of RAVALE in various dictionaries:

The Ruckers family (variants: Ruckaert, Ruckaerts, Rucqueer, Rueckers, Ruekaerts, Ruijkers, Rukkers, Rycardt) were harpsichord and virginal makers from the Southern Netherlands based in Antwerp in the 16th and 17th century. Their influence stretched well into the 18th century, and to the harpsichord revival of the 20th. The Ruckers family contributed immeasurably to the harpsichord's technical development, pioneering the addition of a second manual; the quality of their instruments is such that the name of Ruckers is as important to early keyboard instruments as that of Stradivarius is to the violin family. In the 18th century, Ruckers instruments were often modified by French makers in a process known as ravalement, to allow for an extended range and other additions.
