on my Eichentopf bassoon
The experiment is not over. Though I was impressed, I noticed a much more significant difference on my Heckel, and from Jo Ann’s description of their effect on her bassoon there may be a much better combination for my Eichentopf.
“But wait a second, Andrew, is this historical?” Technically speaking, no. These days, however, I am performing my own compositions for the Eichentopf bassoon often enough to warrant the search for any small improvement to ease playability. My compositions test every dimension of the instrument – from dynamics, to technique, range, and articulation – and any help to better facilitate a performance would appreciated.
So if you have the chance to try the Lefreque plates, no matter what century your instrument is from, I would recommend taking it. You never know what you might discover.
