| The tones are really not as difficult as people make them out to be. 90% of the effort in learning any language is just learning massive amounts of vocabulary. Things like tone and grammar are the very basics that you learn right at the beginning.‡ Beginners complain about them, but after a few months of studying Chinese, you should be fairly comfortable with the tones. Then, you spend years learning vocabulary. The two things that make Chinese difficult are: 1. The lack of shared vocabulary with Indo-European languages (this obviously doesn't apply if your native language is something with more shared vocabulary with Chinese). 2. The writing system, which because it's not phonetic requires essentially the same level of effort as learning an entirely new language (beyond spoken Chinese). ‡. The same goes for grammar issues (like declension and conjugation) that people always complain about when learning Indo-European languages. These are the very basics that you learn early on. Most of the real effort is in learning vocab. |
Disagree slightly with this- pronouncing the tones individually and getting to the point where you can be understood isn't too hard (well still hard), but combining them when speaking more quickly is more challenging, especially if you want it to flow nicely, and adding emphasis while maintaining the tones. Not that it's mandatory if you just want to understand/be understood, it depends on one's goals.
It's a common misconception that it's enough just to learn the tones and move on and it's very hard to find teachers who are able to help with more advanced pronunciation
