German Umlauts

Ich finde es eine Umlaute Herausforderung Umlaute auszusprechen.
Hier ist, was ich über sie gelernt habe:

ä = "e" , it can be a long "ay" like in the word wählen or a short like the word "Hände"

ö= ö (short): Köln as in early (with a more rounded mouth)

ö (long): böse as in burn (with a more rounded mouth)

ü (short):Mütze (like saying ee with rounded lips)

ü, y (long): üben, Typ as in French rue

[In general, all German vowels can be long or short; this is indicated by various forms of spelling of the consonants after the vowel (doubled consonant = short vowel, -h = long vowel, etc.) The long vowels are usually more open, the short ones are more closed.]
