There is a song that can help a person to learn the German alphabet. Similar to the English alphabet song, the song provides the correct pronunciation for the 26 German letters.
The normal and slow versions of the German alphabet song can be found on the University of Portsmouth's Paul Joyce's page. There are individual pronunciations of each German alphabet by a native German speaker. Paul Joyce's page also includes various German pronunciation exercises that include tongue twisters, anglicized words and city names.
Barbara MacArthur's version of the German alphabet song can be found on Songs for Teaching. There are also German pronunciation songs for the seven basic colors, food, days of the week and numbers up to 30 in rap style and others.
