A Treble with 'Single Holes'.

A Herwiga Treble (Alto) with single holes.

This pearwood treble has single holes but NOT German fingering. (The two often go together.)

This old (original) 'Herwiga Chor' model is much better than
the more recent dark varnished ones that I am familiar with.
It plays as a 'baroque' model despite it's 'renaissance' appearance.
