I would like to start learning Cantonese for I am already pretty much fluent in Mandarin. Can you break down the tones of Cantonese very basically? Thank you!

There are 6 different tones in Cantonese. You must rise, maintain or lower the relative pitch of your voice to "sing" each word. For example, in English we naturally use a falling tone at the end of a statement (You came.) and a rising tone at the end of a question (You came?).

To be understood in Cantonese, it is essential that you master the six tones. If you use the wrong tone, you are probably saying a completely different word.

For tone chart go to http://www.cantonese.ca/tones.php

High level (ma)
High falling (mà)

Mid rising (má)
Mid falling (ma)

Low falling (màh)
Low rising (máh)
Low level (mah)

Since you're familiar with ???, you should find it easy.
???Cantonese, ???Mandarin.
(ngo nang waa Cantonese, ngo m waa Mandarin)
(I can speak Cantonese, I cannot speak Mandarin)
