The standard transposition results in movement 2 of Duetto 1 coming out in 5 flats so a version in 3 flats is also provided. This upsets the key transition to the next movement. The last movement of No.3 has a high G-flat which requires a 'knee fingering'. This cannot really be avoided. These file(s) are part of the Werner Icking Music Collection, and are also included in the Mondrup Recorder Collection.
