|Instruments||Strathmann flutes, modern keyed recorders.|
|Notes||A patent for a fully keyed recorder was taken out in 1988 by the saxophonist Arnfred Rudolf Strathmann who adapted the elaborate keywork and fingerings of the saxophone the the recorder (see front view). With his co-worker Klein in Kiel, a series of 'Strathmann flutes' was been developed with many modern features. The body is made of wood or durable plastic, the block height is adjustable with a simple thumbscrew, and the thumbhole is replaced by a key which opens two small holes high up in the head piece which raises any fingering of the lower register to the octave above (see side view). The volume of sound for all notes is stronger than on conventional recorders, and the timbre is said to be between that of a recorder and flute. Strathmann flutes have been made in both soprano and alto models.|
An inerview (in German) with 'Rudi' Strathmann can be found here. A video of Rudi playing his Strathmann flute can be seen and heard there. The Strathmann website appears to be inactive at 20 January 2021.
The firm Mollenhauer have recently incorporated the patented Strathmann adjustable block in a newly designed alto recorder
