Here's my version of the "ABCs" in Spanish, a version of which I have sung with my classes for many years. Copy and paste the text below onto a slide if you would like a quick guide to order and pronunciation. Note the ! mark on a couple of the "gotcha" letters. This song contains the digraph "rr," because it was in the text we were using. Your version of the alphabet may not.
G ge !
H hache !
W doble ve
Y i griega
I also have the post 2010 RAE-updated alphabet for sale, if you are trying to teach that version. It uses a completely different tune.
