Even if you're a seasoned guitarist, it's still hard to hear exact notes and it can be difficult to determine whether strings and notes are flat or sharp. A chromatic tuner is an electrical device that you can plug into your guitar using a standard 1/4" instrument cable. Chromatic tuners can be purchased at most music stores or online.  If you can't buy a tuner, there are apps online that may also act as a tuner.  Some tuners will work with electric and acoustic guitars. If you want a more exact tuner, you can purchase a strobe tuner. The standard tuning on a guitar starting from the thickest string, or the 6th string, is E, A, D, g, b, e. Plug the 1/4" cable from your guitar to the input of the tuner. Strum the top string on your guitar and rotate the tuning knobs on the headstock until your tuner's needle is in the center of an E note. Continue to do this to all of your strings until your guitar is in the standard tuning. Tuning your guitar in standard tuning will enable you to hear if notes down your neck are flat or sharp. Now move down your neck and hold down the 12th fret on the high e string. The note should be the same as it was when you played the open string. If the needle on the tuner is left of the 12 o'clock position, your string is flat. If the needle is on the right side of the 12 o'clock position, it means that your string is sharp. Check the other strings to see if they are in tune just as you did with the high e string. Take note of whether your strings are flat or sharp so that you can make the proper adjustments when setting the guitar's intonation.

Q: Break out your sunglasses when it’s bright outside so that your vision remains unimpaired. High concentrations of UV rays are damaging to the eyes, and they can also be a nuisance while driving or performing other tasks. Since this is the primary intended use of sunglasses, their level of protection should be something you consider when selecting a pair.  Make sure the sunglasses you buy are polarized. This means they’ll eliminate the glare of reflected light.  Keep your sunglasses somewhere close at hand, like in the glove compartment of your car or in a case that you can slip in your pocket. That way you’ll have them when you need them. Find a pair of sunglasses that will hold up to the rugged use of sports or outdoor activities. In addition to blocking out the sun, they’ll also provide a barrier between your eyes and whatever dirt, debris or tennis balls that might be coming at you. Brands like Oakley, Roka and Spy Optics are well known for their sport-inspired eyewear, especially in “shield” and wraparound styles. When buying performance sunglasses, decide on the depth and color for the lens tint that will be the most beneficial for the activity. Complete your look with a pair of shades that accentuates your clothing. Sunglasses are a visual aid first and foremost, but when worn correctly they can also fulfill the role of other accessories like hats, belts and watches. Look for glasses that are consistent with the style and colors you’re dressed in. If you only plan on owning one pair, make it a neutral design that will go with a wider variety of wardrobe choices.  Keep your eyewear consistent with the rest of your clothes. It would be silly to wear a pair of brightly-tinted cycling goggles with a suit. Match your sunglasses to your outfit the way you would your shoes or belt—brown frames go with dusty earth tones, navy and olive; black or metallic frames go with black, white or gray attire; brightly-colored frames shouldn’t clash with the other colors in your clothing, etc. Those who wear eyeglasses can have the lenses of their sunglasses formulated for their individual prescription. That way, you’ll never be forced to choose between seeing and shielding your eyes from the sun, and you’ll look dapper to boot. Prescription sunglasses will be the most useful for people who spend a lot of time outside and frequently wear sunglasses as part of their daily ensemble. You can also get prescription sunglasses with photochromic or graduated lenses, offering a middle ground between normal eyewear and stylish flair.
A: Wear them on a sunny day. Protect your eyes during recreational activities. Tie your outfit together. Have them made to fit your prescription.

Article: Attacks in Dark Souls are deliberate, slow, and usually cannot be canceled. This is true for both you and your opponent. The best time to strike is following a heavy attack that leaves your opponent open. Your attacks are also slow, so be conservative with your attacks, lest you leave yourself with an opening as well.  It may be advantageous to try and keep your distance for a bit and observe an enemy’s attack patterns to determine when there are openings. Always keep an eye on your stamina when attacking. Some attacks from particularly large enemies may break your guard. In these scenarios dodging is a superior option. Parries can be used once you have gained a sense for the timing of your opponent’s attacks for a critical strike.  Not all attacks (especially by bosses) can be parried. A missed parry will leave you open to attack. The risk is great, but so is the reward. Blocking is easier for beginners, but a well-timed dodge is a better way to get into a good striking position. Lock-on is a tool, not a requirement. Sometimes it can be advantageous, especially against larger enemies, to forego the target lock for better maneuverability and camera control. You can toggle target lock on and off as many times as necessary in the middle of a fight, but remember that target lock does have a range limit. Stray too far and you won’t be able to relock until you move in close again. Many of the enemies in Dark Souls will take extra damage from Fire or Lightning attacks. Often you will need to experiment to discover which enemies are weak to what if you don’t want to look them up. Using firebombs is a cheap and safe way to check for fire weakness.
