how do train your voice to get all the high notes that you cant reach
focus on your breathing work at it slowly dont strain your voice or youl hurt your vocal chords
and like itallianabella said,,get a singing teacher because it will help
dont try it by yourself, youll hurt your vocal chords, go to a voice teacher and she/he will help you get up to it, it takes several years to develope a high voice like you want
