Article: There is very often also something new very near the end. Locate passages that you find especially rewarding. Are these passages repetitions, variations, or new? If they are variations, can you realize what it was that was varied? More importantly -- why is a certain section being repeated at all? Is it because the melody is great, or to make a point with the lyrics?   Melody is simply a collection of notes, like the beginning of "Seven Nation Army" or the vocal notes repeated in a chorus. A catchy melody, is usually the key to whether or not a song catches on.  Harmony is the collection of notes played at any one time. Some people think of it as "vertical," whereas melody is "horizontal." How do multiple voices, instruments, and notes come together in one instant to harmonize, or sound great on top of one another? What are the intangible feelings the song gives? Start simply -- is it happy, or sad? Do the instruments sound bright and bouncy, or thoughtful and somber? What sort of scene to you imagine the song being played over -- rainy, sunny, joyous, thoughtful, heartbroken, etc. Some terms to keep in mind include.   Colors: It may be hard to see color in sound, but close your eyes. Imagine the song is in a movie scene -- what is the dominant mood or color of that scene?  Balance: How many instruments are playing at once? Is it spare and sparse, the beginning of "Hey Jude?" Or is it big, bold, and filled with noise, like the end of "Hey Jude?"  Texture: A guitar can be "chunky" or "smooth," a trumpet solo can be "silky" or "abrasive." Mostly this comes from the rhythm -- are their long, well-held, smooth notes, or are they all short, choppy, and distorted? Notice things in the bass that seem alive, pregnant with meaning, or just sound cool. Notice the kinds of changes that happen at your favourite moment. Does the melody soar into an unfamiliar accent? Does a new rhythm add pungency? Does a buzz suddenly splinter into a fractured collision of noise and excitement? Does the song end up in the same, or a similar, place as where it started? Or does it tell a story, moving and evolving so that the singer feels "changed" from beginning to end. Both are viable types of songwriting, but both tell very different stories. If the song does seem to change, ask yourself how the singer and musicians made the "argument." At what point is there a shift in the overall idea or feel of the music? The key change in "Hey Jude" is one of the most important, and famous, instances of movement and change in pop music. In an instant, the song goes from somber and thoughtful to joyous and intense. Songs are not written in a vacuum -- and sometimes stepping into the context of a song suddenly makes the lyrics make sense. For example:  Eric Clapton's "Tears in Heaven" gains even more power when you know it is about his tragically deceased son. Kendrick Lamar's "Blacker the Berry" is a searing personal letter written right after Trayvon Martin was murdered. If you do not know the huge political and social ramifications of that case then the song likely falls on deafer ears. Getting into jazz, classical, prog rock, or any other musical form with 10 minute songs, is daunting. Don't worry if you get distracted or even a little bored at first -- it is only natural. But push yourself to focus on each section on repeat listens. Composing these pieces is no mistake, and the composer is trying to fill the time and pull you along with the song at every second. While they might not always succeed, work on focusing throughout the whole song. You'll be surprised at the subtle, exciting bits and pieces you pick up. Try out Duke Ellington's "Diminuendo in Blue," to get started. It is long, but high-energy and exciting throughout, with well repeated themes and melodies.
Question: What is a summary of what this article is about?
Recognize and listen for repetition and variation. Think carefully about the tone, mood, and feel of the music. Listen in for specific instruments, noting how the parts come together to form a greater whole. Think about the song's movement, or progression. Search for any crucial outside context about the track. Build up your musical concentration for longer pieces.

Problem: Article: A lot can go a long way, so you only need about 1 to 2 tsp (5 to10 ml) of ketchup, at most.  Use a soft cotton or terrycloth rag for best results. Tomato juice is a mild acid, so the use of tomato-based products can help dissolve debris causing tarnish and dullness on your brass. Ketchup is your best option since it is so thick, but in the absence of ketchup, you could also try tomato paste or tomato juice. Wipe the sides of the brass object down with the ketchup-covered cloth, coating all sides in the ketchup. For best results, rub the ketchup on in a single direction instead of rubbing it on in a back-and-forth motion or a circular motion. Use a damp cloth to wipe off the ketchup after allowing the tomato substance to sit on the surface for a couple of minutes. You could also rinse the brass under running water to get the ketchup off, but using a damp cloth provides the added benefit of a little extra buffing. Use a dry, soft cloth to dry off any remaining moisture while giving the brass a final shine. Thoroughly buff the entire surface by passing over it in small, circular motions.
Summary: Squirt a dollop of ketchup onto a soft cloth. Rub the surface of the brass with the ketchup. Wipe off the residue. Buff until dry and shiny.

Much like Windows, Linux has support for four-digit codes that call special symbols. To access the code input, place your cursor where you want the dash and press Ctrl+⇧ Shift+U. You will see an underlined “u” appear. Enter the code you need and the symbol will appear.  To create an en dash, press 2013 and then press ↵ Enter. To create an em dash, press 2014 and then press ↵ Enter. If your keyboard doesn't have a dedicated Compose key, you can assign a key on your keyboard to become the ⎄ Compose key, which will allow you to quickly create symbols. You should pick a key that you don’t typically use.  To map the ⎄ Compose key, open your Settings in Linux, and then select Keyboard Layout. Click Options and then assign a key on your keyboard to be the ⎄ Compose key. To create an en dash, press ⎄ Compose and then --. To create an em dash, press ⎄ Compose and then ---
