Speaking of German, the transverse flute often carried that name tag as well for some reason not easily explained.
Further confusion arises from the application of range terminology for flutes.
The recorders, for example, were designated by size as they relate to each other, but in relation to vocal range, they are an octave higher than their designation implies. The transverse instruments also have a tradition of terminology that is more fanciful than descriptive. Like the bass recorder, it is really an alto voice in its lowest register. Another example in the Miller collection captions the G bass in the other direction. The other five included three variants of the Boehm system.
