Mariah Carey, born March 27, 1969, is a pop and R&B icon known for her five-octave vocal range and signature whistle notes, the highest vocal register above C6. Her hits like 'Emotions' (1991) and 'Hero' (1993) showcase these piercing, controlled notes, used sparingly for impact. With 19 #1 Billboard Hot 100 singles, she’s a songwriting and producing powerhouse. Her whistle notes, blending power and precision, cemented her as a vocal legend in the 90s and beyond. #studiosession #mariahcarey #leg
