A radical change took place in the design of Western European flutes in the mid-nineteenth century. The instrument's projection and roundness of tone were substantially improved by a key system developed by Theobald Boehm. However, the system required players to learn new finger combinations, and a number of transitional designs were developed to ease the process. The key system on this instrument was invented in 1870 by John Radcliff, a British flautist and inventor. The keys for the left hand are similar to the new Boehm system, while the keys for the right are based on the earlier (and more familiar) simple system. Radcliffe wrote of his design: 'I am aware that there are still many Flute Players trembling on the verge of a transition from the old to the new class of Flutes, desiring, but hesitating whether or not to take this step…To all such I may not be considered presumptuous if I hold out my hand and say, follow me. I have gone through all your experience, have stepped over the stream before you, and have now planned a bridge by which you may pass over still more easily.'
