The Family Tree's chief purpose is to give a clear picture of the history of our brass instruments in Europe. The line of descent is sufficiently clear among the natural instruments of the first 3 groups, i.e. of the cornetts, the trumpets, the trombonesand the horns, even after the introduction of keys. Difficulties arise, however, with the invention and application of valves. Many of the valves instruments are "cross breeds" and, as such, extreemly difficult to classify. -the publisher
