I_I6 vi bVI+ I64 viidim7/V_V7 I
(if you can make that out)
Measures 14-17 in Hensel's "Nachtwanderer" use a few examples of modal scale degrees. In measure 15, beat 2 contains a D flat, while in measure 16, beats one and two have an A flat and B natural. Measure 15's D flat functions as a chromatic passing tone between the D of beat 1 and the C of beat 3 and even into the B natural of measure 16. In Measure 16, the A flat and B natural form a vii dim7/V. This diminished chord, which is not a modal mixture, also happens to be on the word "grau", meaning gray, coloring it with a very dreary sound.
