How many octaves are there in Whitney Houston? Is Mariah Carey really better than Whitney Houston and celine dion? I always feel that dolphin sounds are not true sounds.

Five octaves, high quality, known as the "Voice of America". Menstruation is called the "Queen of Soul" and Maria Kelly is called the "Tenor Queen". Although her tenor is slightly lower than Maria Kelly's, her range is much wider than Maria Kelly's. Marika Kelly is good at dolphin sounds, and Aunt Hui is good at high notes, which are different concepts. Besides, Celine Dion, Celine Dion can't compare with Aunt Hui and Mariah Carey. Celine Dion is also a diva, but she is still a few grades behind Aunt Hui and Mariah Carey! (pure hand, hope to adopt)
