INPUT ARTICLE: Article: . The 52 white keys on a piano keyboard are called according to the name of each key's associated note. Notes range from A to G ascendingly, so letters increase moving to the right on the keyboard (as in A → B → C) and decease moving to the left (as in C → B → A). Furthermore:  Once you reach the end or beginning of the note sequence, it repeats. So when moving to the right up the keyboard, G → A → B, whereas moving to the left yields A → G → F. The 36 black keys on the keyboard represent a half-step difference in tone between white key notes. A sharp (♯) is a half-step up, and a flat (♭) a half-step down. Therefore, the black key notes have two different possible names. For example, the black note between F and G could either be called both F♯ or G♭.  Easily locate the C note on your keyboard by finding the white key immediately to the left of a group of 2 black keys. The C key closest to the middle of your keyboard should be middle C, which is a central note for most beginner level songs. In many songs, you'll find small numbers above or below notes. These numbers indicate the recommended finger you should use to play the note. Very basic songs many have finger notation for each note, while more complex songs may have little finger notation. Each number represents a single finger:  1: represents your thumb 2: represents your index (pointer) finger 3: represents your middle finger 4: represents your ring finger 5: represents your pinky When first beginning, you may find it a little difficult to play a finger when you read its number. This is common, but by learning finger notation thoroughly, so it is automatic, you'll find playing easier.  Many beginning students find scale drills an effective way of learning proper finger positioning. A scale is an uninterrupted run of notes, usually in 8 note increments, that moves up or down through a musical key. As many basic piano songs have a lot of finger notation to assist beginners, you may want to make use of these resources to practice. Keep your fingers slightly curved but firm so that when you press a key your finger does not bend backward at all. Your thumb and pinky fingers especially will want to lie flat, but keep these raised as well.  Try to keep your arms and shoulders relaxed as you play. This will enable you to use more of your entire body while playing and will help you achieve a better sound from the keyboard. As you press a key, you should feel the weight from your arm transferring down into the key through your fingers. Although you might think that the position of your fingers doesn't affect your playing much, the proper form will allow more freedom and nuance in your playing.

SUMMARY: Learn the keys on the keyboard Make sense of finger numbers. Practice finger notation so it is automatic. Position your fingers and hands with proper technique.

INPUT ARTICLE: Article: No quickly constructed shelter will help you from winds at this strength. Instead, go to a basement, or failing that to a room near the center of a building with no windows. A shelter is usually not the best option for an earthquake, although you can prepare in other ways. Earthquake survival is based on two main strategies:  If the tremor is mild and there is a relatively open space outside (no tall buildings), walk to it through the nearest exit. Do not use elevators. If the tremor is violent or you cannot reach an open space safely, drop under or next to sturdy furniture and hold on. If you own a house and are committed to disaster preparation, dig out a basement or dig a bunker. Stock this with emergency supplies in case ordinary services are disrupted. You can also get a FRS or ham radio (you need a license though) for communication. An underground bunker is your best bet for protecting yourself from radioactive fallout. In general, the safest areas are indoors, with as many walls and thick furniture between you and the outdoors as possible. Insulating the walls with as much dense material as you can find will protect you further.Seal all vents using duct tape and try to close all doors.

SUMMARY:
Identify hurricane or tornado shelters. Come up with an earthquake plan. Construct a long-lasting shelter. Learn how to survive nuclear fallout.
