Classical

I have to go for the obvious, and say the 1812 Overture and Bolero, both absolutely epic, especially when you are watching a live orchestra.

Mozart, Bach, Beethoven, Handel, Chopin, and Brahms are all from either Germany, Austria, or Poland. Was there just a greater cultural emphasis on music? Or maybe some sort of famous music education center in that area? I feel like it isn’t coincidence that all of the most famous classical composers were born within a 300 mile radius of each other. 

Any help and advice is appreciated

No, minor and flat are not the same thing.  

It's called Für Elise. There are lots of renditions on YouTube including https://www.youtube.com/watch?v=wfF0zHeU3Zs

Who should I get into first? I want pieces that I should listen to first and if you have any other classic composers that you like add them in.

Apparently your brainwaves are more agitated whenever you're listening Beethoven. Your brainwaves feel more relaxed when listening to Bach.

Is a composer the person who writes the music in a musical or the person who writes the words that are sung in music?

In have known people here is the US with the first 3 surnames.  Only the Brahms is a fine musician. There may be others.  I also know people who are musicians named Schubert, Tchaikovsky (variant spellings) and others. Sorry for typos . . .

Try some Mozart. You can't go wrong with Mozart, it's all pretty awesome. If you want something a little different, try Gustav Holst, the Planets suite. He was late 19th - early 20th century, and this is his most famous work, each movement is inspired by a planet, Mars, Jupiter, Mercury, etc. It's one of my favorites.

What is the most beautiful piece you've ever heard? What brings you the most?

Every day - it is our career.  When we are practicing, each of us can hear the other - unless we go to our own studios at opposite ends of the house, and close both doors. Then there is what we listen to for enjoyment, which also includes some jazz and other things.  A lot of people assume that classical musicians listen ONLY to classical music - but that would be like a chef in an Italian restaurant, swearing to never eat Asian food, or BBQ.
