This fingering serves for both D#4 and Eb4. Note that, even with just one hole open, some of the regularity of the response curve for D4 has disappeared. The fifth and some higher minima are less shallow and not harmonic. Thus the higher harmonics are weaker than for D4, and so the tone is noticeably darker.
