Vertical flute

The vertical flute is either (1) a rim-blown (notched or un-notched) flute, (2) a tubular duct flute, with tapered bore or (3) a transversely blown flute, Giorgi flute, designed to be played in an upright position. The vertical flute is contrasted with the "cross flute" (or "transverse flute") and "globular flute", and in stricter usage may refer only to the first category above (Marcuse 1975, 187).
