This is a pretty broad question. It really depends on what era of music we are talking about but overall I'd say using different instrumentation creates a great variety of sounds for composers and using a wide variety of tempos and pitches keeps it interesting.
Two of the most obvious musical elements that composers use to achieve variety are indeed dynamics and timbre. These can be achieved by using different instruments in different registers.
The leading classical composers in French music include Bach, Mozart, and Beethoven. Other obvious choices for classical composers include Verdi and Wagner.
F can either mean flat = b or forte which means loud. When seen in a musical score it almost always means loud. You will sometimes see ff, or fff, and the meanings are intuitively obvious.
The piece makes deliberate compositional mistakes. Some are obvious like wrong notes, others are more subtle like banal development of themes or irregular phrases. It's cute but not hilarious and it helps to know other music of the period.

There are many jobs that involve musical instrumentation. Apart from the obvious one of being in a band, you can also be a music teacher or work in audio-visual teams for the TV and film industry.
In what country, in what time period are the two obvious elements you left out of your question.
I think that might be obvious the dark side use the elements of the force but use it in a evil dark way. They get their ideas from death,destruction, and despair.
valance, although there is lot of variation here as well.
I would hope that "chromium" is obvious. Slightly less obvious is that "oxide" refers to the presence of oxygen.
If the elements (which were discovered by his time) were organized in the increasing order of their atomic weight, they will exhibit an apparent periodicity of properties. It also had the ability to predict physical and chemical properties of some undiscovered elements.
Because there are only 26 letters, 22 of which are usable (A M R & X are reserved for various purposes). With around 115 elements at last count it is obvious that 2-letter symbols are needed for most of them.
You need to adapt to your environment for various reasons. The most important and obvious one is that you need to do so in order to survive and not die due to the elements.
