The observations of the Moon were taken on four different days in the month of February to March capturing four different Moon Phases.

I would also consider shifting work outside the period traditionally reserved for closing activities. I would review the closing activities to determine which ones could be shifted to the previous months and which ones can be delayed until after close. Implementing automation can also shorten the closing process.

Because the mind is not involved in this physiological process, one can only begin to describe why we get "pumped," why our heart rates increase or why our moods change when we hear a certain piece of music. In the conversation in Chapter 6, each student seems to have a different way of describing how music makes them feel, which supports my belief that each student has a unique physiological approach when listening to or performing music that is unlike that of anyone else. As the chapter mentions, there is no true explanation as to why some people get goosebumps when a certain song plays and others do not.
