Soprano c'', Alto g' and Alto f '
The "Ganassi" recorder is a model developed by several makers in the 70s.
It has a range of more than two octaves, and plays with a fingering known nowadays as "Ganassi fingering", an adaptation of different fingerings present in the treaty of Sylvestro Ganassi, Opera Intitulata Fontegara, 16th century.
The "Ganassi" recorders I make are based on the model that the famous
australian recorder maker Fred Morgan developed after one alto recorder in the Vienna Kunsthistorisches museum (inventory number: SAM 135)
It has a cylindrical body, with a conical bell at the bottom. The sound is strong and stable, especially in the lower register, and the higher register has a brilliant sound.
The "Ganassi" recorders are made in two parts, head and body joint, with a brass ring, and allow the use of two different bodies in pitches 415Hz, 440Hz and 466Hz.
For the sopranos I use maple, pear and european boxwood, for the alto'
maple, cherry or pear, both work equally well.
