In one sentence, describe what the following article is about: You can buy strings in a variety of thicknesses, tensions, and styles. Experiment some with different sizes to get a sense of what sounds best with your particular style of playing and your wishes for your sound. Thicker strings put out more volume, resonating with a thicker vibration, while thinner strings tend to be brighter and sunnier. Try a set of each and see what you like. The most basic form of strings used on violins are made of steel alloy, often wrapped in nickel. The higher E string is usually plated with some other metal. They tend to have less stretch and durability than other strings, but are by far the cheapest and most widely available strings you can buy. They're most recommended for beginners and if you're changing a string for the first time. With a warm sound a quick response, the next step up in the market is rope core steel, which is similar to steel core strings, but braided from more material, giving the player a bright, clear attack on the strings. These strings are commonly used by fiddle players. It doesn't get any more visceral than this: gut strings are made of the intestinal tissue of sheep or lambs. While somewhat gross, these strings feature an incomparably warm and lively sound. Gut strings are somewhat fussy, requiring lots of tuning adjustment. They're greatly affected by weather and temperature as well, making them more useful for very experienced players. Combine with a traditional horse-hair bow and you'll be playing with the same basic ingredients as the old masters.

They're also somewhat expensive. Most players will put the variety of string on the instrument, while some experienced players like to use particular strings in the E slot for tonal reasons. Violin companies Hill and Westminster make E strings available separately from their respective sets and are popular inexpensive choices to experiment with.
Summary: Experiment with different gauges. Consider steel core strings. Take the next step with rope core steel. Go old-school with gut strings. Step into the future with synthetic strings. Think about your high E.

In one sentence, describe what the following article is about: A macro lens will allow you to best capture the detail of the eye. Macro lenses vary in focal length from 50 to 200mm. You can still take a good close-up photo of the eye with a regular lens, but you may not be able to get the eye to fill the entire frame or capture all the detail you want. If you don’t have a macro lens and don’t want to spend the money to get one, try using a close-up filter as an alternative. Many cellphones have a macro mode, which will allow you to take a more detailed photograph of the eye than with your camera’s standard settings. A macro lens attachment for your cellphone will produce even more detailed shots.  You can find a macro lens attachment for your cellphone at most major retailers and electronics stores. If you’re planning to buy a macro lens attachment, make sure you choose one that fits your phone model. Extension tubes fit between the rear mount of the lens and the camera body. Using an extension tube will magnify the eye in your shot, allowing you to capture more intricate details.
Summary: Put a macro lens on your camera. Use a macro mode or macro lens attachment when using a cellphone. Consider adding an extension tube to make the lens focus closer.

In one sentence, describe what the following article is about: Combine these four ingredients in your blender and mix on a medium setting until they are well combined. This could take about 15 to 20 seconds.  Using yogurt instead of ice cream reduces the fat content of the shake while adding more calcium and probiotics.  Using low-fat or nonfat milk cuts down on the number of calories in the shake. Natural sweeteners like raw honey and agave reduce the sugar and number of calories in your shake. The result is a shake with a low glycemic index, making it safer for people with diabetes or those who are at risk for diabetes. Drop 2 or 3 drops of green food coloring into the shake and blend for another 10 to 15 seconds, or until evenly dispersed. You can skip the green food coloring altogether if you are worried about including dyes in your food. Add 5 ice cubes to the blender and blend on high until the ice is fully chopped and dispersed through the blender. This could take a few minutes.  If the shake is not thick enough to suit your preferences even after the ice is mixed in, blend in another two ice cubes. Note that you may need to pause your blender and stir the contents with a rubber spatula to ensure the top and bottom of the mixture are being evenly blended. As soon as the shake is done, transfer it into a serving glass and enjoy.
Summary:
Blend the yogurt, milk, mint extract, and sweetener. Add the green food coloring. Blend in the ice. Enjoy immediately.
