In the The Great Big Rump article I can relate to when it talks about not being able to focus on work and at the same time thinking about my posture and multiple other things. When working on homework I often do not think about my body or position until I start to get sore. 

I also find it interesting when the article said “But that lump of flesh is doing exactly what you are doing (it is you!), it's not really engaged in its surroundings because you aren't either.” I think this is very true. When I'm not focused on my surroundings I end up slumped and not really moving around a lot.  
In regards to the By Intention Alone article:
In a way I can understand how your thoughts can direct your playing, or in the writers case her singing. For example, when I am playing french horn and I have to pitch and hold a note. I sometimes start worrying about pitching it correctly and when this happens I tend to crack or not pitch it correctly at all. But, when I have less time to think about the pitch I am able to pitch it correctly. Thus, I understand where the writer is coming from. Although, I do not agree with the idea that a person should not do anything about the problem. For example, I do not agree with the writer when she says,
“I really don’t want to “do something” to get a bigger sound. I know I don’t want to do that because I know that once I do that it means that I’m going to have to do that every single time if it’s successful. I just don’t want to get busy with that.” I do not agree with this way of solving her problem because to me it just seems lazy. If you find a technique that works and does not damage your voice than why shouldn't you use it over and over again? If you do this eventually it will just become apart of how you sing, which is more reliable. It is more reliable because your body reacts differently in different situations. For example, let’s say she was in a situation where she was singing in front of people she was not comfortable with, her body would react in a different way. Thus, telling her body that she wants it to sing louder might not have the same outcome. For instance, I am currently trying to work on pitching these two notes in a solo I have in band. Sometimes I worry about missing the note or cracking it and when I worry about this I usually end up cracking it. But, instead of not thinking about it, or trying to say to myself do not crack, I try to hear/sing the pitch in my head before I play it. This technique is a lot more reliable because it will work in almost any situation because it’s built into me. When I do this enough it becomes muscle memory, so when I hear the pitch my lips automatically know what position to go to in order to make the pitch. Thus, making this technique more reliable. Also, in the long run will make me a better player because I will know my pitches better.
