J. R. Lafin began his career as a flute technician in 1979, becoming the only flute repair speciailist in Berlin at the time. Subsequently, he was able to go to Japan where he received extensive training at the Muramatsu factory. Through his contact with many flautists he often heard criticism about headjoints, except when they were made by Albert Cooper. This inspired his specialisation in head joint manufacture, beginning to make headjoints himself with his own custom made tools.
Following a long period of experimentation and trials, a partnership began with Albert Cooper making headjoints to his design and specifications. Since Mr Lafin and Mr Cooper are continually adapting their designs and experimenting with new ideas to improve playing characteristics, the design is always changing slightly in an ongoing effort to make flutes play better.
J Rainer Lafin headjoints are played worldwide by some of the most highly regarded players.
