Robertmetal,
I think Tim and Darrison summed it up and we have run this full circle before on vc forum. Let me cut to the chase, yet again.
Why would I not want to sing with a "balanced" posture, BECAUSE I DONT LIKE THE SOUND/OVERTONES it produces, its too "hooty" and its not aggressive enough for what I want to do as an artist and what 90% of my students are asking for. THATS THE PROBLEM, I dont know how many different ways people can make this point on this forum.
That doesnt make projected vocal sounds wrong. It just makes it wrong for me (most of the time, depends on the tune) and a lot of people that want more "cut" in their sound.
Can I sing with a lowered larynx? I can. Im a professional, I can sing with a distorted twang or a flutey-hootin, balanced posture tone,.... I have also had some exposure to SLS, I have 4 years of Classical, lowered larynx exposure... I "get it"... I just dont dig it as an artist and its not what my voice pedagogy is about.
However, I demonstrate both configurations and their unique sounds ever day in my training because a student has to be able to hear both configurations to learn how to twang...Once you learn how to twang you then can calibrate for how much you want. Its not all or nothing. As a singer and a teacher, you want to be able to demonstrate both!
The point that any kind of muscularity is wrong is an error. Isolated AES contractions are fine and lower torso anchoring are also perfectly fine. Both are commonly seen in extreme singing and understood to be ok by most vocal experts today.
In regards to our TVS videos, my students and I lead by example. We are not afraid to put our selves out there and show what we got. I dont ask my students to do anything Im not prepared to do myself and I think thats an important part of leadership and certainly one of the things that makes TVS special. I admire students and especially teachers that are/can actually sing and have the guts to put themselves out there to demonstrate. It adds "moxy" to their credibility in my opinion. Actions speak much louder.
