The Cantonese pronunciation is the same as "Yue", "E", "Crocodile" and "E"

The Cantonese pinyin is probably: eo (4th tone)

"e " and "o" are both pronounced in Mandarin Pinyin

You can pronounce "e" first and then "o". After reading it a few times and then reading it in succession, you can spell out the Cantonese pronunciation of "乐".

Disclaimer: I have never learned Cantonese Pinyin. I just spelled it out based on the approximate pronunciation, so I cannot guarantee that this is the correct Cantonese Pinyin
