Actually, Chris has dramatically grown and improved in vocal range. In fact he sounds much more grown and is hitting several new note high and low notes on several of his newer songs. Whats great about him is he has the ability to sound younger or older on hisnewer songs. Chris unlike many R&B singers, has the ability to choose how he wants to sound. Thats a part of what your hearing here. There are many examples of this ciing from him now. Dont get it twisted.
