Working along with my rehearsal tape of the session with Theresa Koon, which I talk about in the post below, I heard again the exact words she used and helped so much:
"See whether you can use the material of your experience singing it--like, 'I'm sharp! I'm flat! I don't know who I am! I can't keep my breath! I'm slouching!'--and have the words be about that."
Somehow this direction drew my attention to the text itself; i.e., I found myself 're-thinking' each word in the lyrics as I sang it as I concentrated on my EXPERIENCE of singing it. When Theresa asked me to describe this, I said:
"I felt like [following the direction] was putting me consciously more on the part of me that's not conscious," or, "putting me intentionally more on the part of me that's not conscious."
Something like that.
