Love to see you so exited after screaming that double G! I just wish I could do the same because I can only scream a high D consistently. Do you have any tips?
Playing my scales and lip slurs definitely helped build up my range above the staff! I always try to stay as loose and relaxed as possible and I try to make all my screamers seem like playing notes in a comfortable range. Try not to press the mouthpiece on your face since that stops your lips from vibrating and the note won’t come out. Hopefully this helps! :)
