Those are the letters, sung using the names. As in English the names won't (always) help with pronunciation, how often does a Q make the kee-you sound in words.

My third teacher had the same pronunciation as this woman singing. She rolls her R from what I can hear. I am on board with whatever helps you learn the language. At one point we all have to choose an "accent"

If you learn English in Georgia or Wisconsin or even London, you will sound good speaking as long as you are consistent with the area you learned from. I am a native English speaker and I understand all of the above plus Irish and Scottish accents. I am fluent in Spanish and have taught that language as well. I understand Spanish from all Spanish speaking countries and they understand me too.

I have chosen (and teach) the sounds of the spoken Hebrew words that I hear read in Israel both read and sung.
