Nothing prevents you from speaking it like a native.
You've essentially reinforced your role in the analogy. You could learn to communicate in English better, you've chosen not to. We can still grok your meaning but the initial impression is a bit of a turn off.
Music is the same. Those little details you've chosen not to learn will be noticeable by other musicians, they'll likely find those traits to be negative. YMMV.
Come on..!!!.. give the guy a break here. None of us know how long he has being learning English. Nor can we say for certain, that he has chosen not to go any further in his learning of English. Can you not give him the benefit of the doubt that it is a "work in progress"? He has obviously chosen to learn, otherwise he would not have posted.
He came on here asking some genuine questions, not..as he says himself...for a finger wagging session regarding his grasp of (to him..) a foreign language.
OP, welcome to Talk Bass.
