Please refer to the following excellent and comprehensive Australian sites for any information on recorders :
Nicholas S. Lander's Recorder Homepage
Malcolm Tattersall http://members.iinet.net.au/~mtattersall/
Orpheus Music https://orpheusmusic.com.au/
Wikipedia - that great fount of semi-peer reviewed information also has a lengthy section on the recorder
For people who only remember the soprano/descant recorder from school - there are at least eight Recorders of varying sizes ranging from the very high-pitched 15cm Garklein to the very deep 2 metres Contrabass.
- Garklein The highest pitch.
- Soprano/Descant The one most used at school, with an undeserved reputation as “screechy” when played by beginners. Fabulous in the right hands
- Bass/Basset in F
- Great Bass
