in order to drive them into your muscle memory, you would need regular practice with scales. are you doing something like that already?
(lip trill, hum, and open 'ah') through my entire vocal range pretty much every day. I haven't been as disciplined about that lately. Instead, I have been doing those warmups to the tune of songs I want to learn. Should I go back to doing them through my entire vocal range each day?
I find I have to lower the key of his exercises because I am a bass. I will also check out the videos in your profile. It's kind of you to listen and share good advice! Have you posted any performances I can check out?
