Pronounce the word "THE" correctly 1

The word "THE" is one of the most mispronounced words by foreigners and it is one of the most important and most common words too.
What´s the deal about "the", then? Most people will never realize that they are mispronouncing "the", even fluent speakers of English.
Let´s remember something first, something that might help.
We use "AN" before vowel SOUNDS (not vowel letters) and "A" before consonant SOUNDS, isn´t that right? It´s the same thing about THE: There´s also an difference in pronunciation, although there is no writing difference.
WHAT?!?!?!!?!?
Examples:
you say THE (THiiiiiiiiiii) apple
THE (THiiiiiiiiiii) other
THE (THiiiiiiiiii) air



and you say
THE (THããããããããã) girl
THE (THããããããããã) student
THE (THããããããããã) business

Got it?
I know, it´s a revelation, right? Just so that you don´t freak out, this kind of pronunciation error usually, usually, doesn´t cause communication breakdowns. Keep practicing this and then your English will sound much more natural.
