 To produce the German long "{e}", open your mouth slightly and position your tongue relatively high and forward in the mouth. The lips should be slightly spread (not rounded). The key is to keep the sound pure and steady — do not let your tongue glide upward at the end. The result should be the German exclamation {he!}. Isolate the long "{e}" sound and pronounce it a number of times by itself.

 The final short "{e}" (called "Schwa") is a very brief, relaxed, neutral vowel. To produce it, relax your mouth completely and produce a very short, unstressed "uh" sound. Listen to the word {Scheine} — the final -e is this brief, neutral sound. Isolate it and pronounce it a number of times by itself.
