Second Bassoon Lesson, Part 2. BDP #31 <Music: Vivaldi's Bassoon Concerto in E minor> We have two different sets of muscles that participate in our breathing in-- inhalation--and breathing out, which is termed exhalation. So let's examine first the muscles that help us breathe in. The costal muscles are those muscles largely associated with the rib cage. Between the ribs we have muscles called the intercostal muscles that help of rib cage expand and move up and out. This draws in air with the lungs. This is a type of breathing that we might call chest breathing. We have another very important muscle that is called the diaphragm. The diaphragm is a domed-shaped muscle that sits underneath the lungs here and when you breathe in, the diaphragm flattens. Here is another picture with the diaphragm down here, and when this particular muscle contracts it draws in air. There have been some studies of the effect of these different sets of muscles. It's largely found that chest breathing accounts for about 40% of lung capacity and diaphragmatic breathing, that is, breathing using the diaphragm contributes the additional 60%. So you can see the diaphragm is very important for breathing and it's important that you learn how to do that. Now normally when we breathe in we use muscles to breathe in and we just relax and the air goes out. However, with playing a wind instrument there is a good deal force that has to push through the wind instrument. (Here we have a little oboe reed pictured.) We need to use the abdominal muscles, the abdomen the muscles in this area to push out--as well as contributors from other areas--here to push out the air. The diaphragm never pushes out air. The diaphragm only brings in air. The abdominal muscles are the ones that push out air. Now I often use the analogy of a bottle when describing a nice slow breath to beginners. You should first fill the bottle from the bottom: that means using the diaphragm to pull in the air. Then as the bottle fills (as it were), as the lungs expand, we allow the air to increase in the chest cavity allowing the chest—the intercostal muscles, and the costal muscles--to participate in that breathing. Obviously when you take a very quick breath both the diaphragm and costal muscles are breathing all together in one very swift breath. OK, it is time to lie down on the floor and practice this other method [diaphragmatic breathing]. So get down on the floor, put your hand on your abdomen. We are going to get a sense of the proper movement of the diaphragm as the diaphragm moves down and pushes the internal organs out. Ah, that is so relaxing. I think I could just go to sleep there! It is important for you to understand the proper use of those muscles. How that feels with those muscles expanding. We don't want you breathing from the shoulders. The shoulders participate in the breathing, but only after the lower part of your body expands. The lungs expand from the base and expand up through the chest cavity and the shoulders simply rise. We want to avoid chest breathing only. We want to use the entire lung capacity that you have. The bassoon is a wind instrument that uses a lot of air. OK,we are coming to the end of our second lesson. It is time once again take the bassoon part. I showed in the first lesson how to take apart the other bassoon and I am going to take apart my bassoon too. Everything needs to be stowed in the right place, so I put away the crutch, the hand rest. You will notice that my case is a little bit smaller. Now next I take the bocal. I actually blow out the water out of the bocal. I put down a piece of paper here so I don't get things too messed up. Put away the bocal. Next comes off the bell joint. Take off my contraption here. Stow that away. Take off my guard. Next is the long joint coming off. Now, I keep a cloth between my two joints to avoid the joints rubbing against each other. Next we take off the tenor joint. This is the thing I wanted to make sure you saw: When you take off the boot joint keep that up[right]. Be sure that you dump the water out from a little hole. I don't have much water here. This part is lined: there is a rubber lining that goes down there. This part is not [lined]. You want to avoid any water touching wood. Well, now it is time to swab out the bassoon. Again you put down the swab in the big hole. It comes out the little hole. Pull it through. And similarly, swab from the big end first. Make sure your swab is not tangled up. Then pull it through. Pull it through this end. We just swabbed out the bassoon. <Music: Vivaldi's Bassoon Concerto, “La Notte”>
