I want to know how to do high screams for metal/screamo music. I really can't seem to get them. My mid's and lows are alright. But everytime I try to go high, my voice cracks >.< Kind of like Shawn from the band Alesana if you know the band. I can do the scream, but I can't keep a good, solid tone going. Anyone have any tips for me? Would really be much obliged. I'm not going to use the vocal fry, whisper scream, whatever you want to call it. I'm not going to screw up my vocal chords, I used to scream that way, realized that my throat kept hurting after like, every song, and found out why. But yeah, as I said, any tips would be very much appreciated please and thank you.
