Oboe

In the first half of the 19th century, the key mechanism of the oboe experienced rapid developments. Whereas in about 1810 models with two keys were still common, in 1825 Joseph Sellner taught how to play instruments with ten keys in his oboe tutor. Thus, with the newer oboes, the range in the low register was expanded to the note of B, and keys for the notes of C sharp, F, (F sharp), G sharp and B flat (as well as the C trill key) were mounted. The ultimate goal was to play all of the slurs in all keys in a technically reliable manner, occasionally with alternative fingering (F key), and with clean intonation. (bd)
