The IPA sound [tʃ] represents a voiceless post-alveolar affricate. In Brazilian Portuguese, it is commonly represented by the letter "ch." To pronounce it correctly, you need to position your tongue near the alveolar ridge (just behind your upper front teeth) and create a partial closure. Then, release the air by moving your tongue quickly away from the ridge while keeping your vocal cords inactive. It's similar to the "ch" sound in the word "cheese" or the "tch" sound in "match."
