+@c Add example of white noteheads:
+@c In the french baroque some composers used white noteheads in slow pieces,
+@c mainly in 3/2-time. A quarter looks there like a eighth with a white
+@c notehead. (Franz-Rudolf Kuhnen)
+
+@c TODO Add example of this:
+@c I was referring to e.g. notated a8. a16, which should, if I
+@c remember correctly, be interpreted more like a8.. a32 (in the french
+@c style). The editor might want to show that rythmic figure above the
+@c staff as an hint to performers. (Karl Hammer)
