Hip to be Square

The picture is of the inside of a circa 1800 square piano in the Royal Academy of Music Museum, but I actually went there to see the Re-thinking The Oboe exhibition. (Some of you may know I fix oboes for a living)
The exhibition shows the development of the instrument from around 1700 up to the present day, culminating with the new Howarth/Redgate oboe upon which it is possible to play 1/4 tones & multiphonics.
One of the exhibits is the instrument owned by Antonio Pasculli, the Paganini of the oboe. It's amazing that he was able to play such fast technical pieces on an instrument with so few keys. Here's Chris Redgate playing Pasculli's Le Api, written in 1874, on a modern oboe.
Still pretty impressive!
