A dot book (also dotbook or dot-book or drill book) is a small notebook utilized by marching bands (especially high school show bands and drum corps) in order to aid the learning of formations on a field. The dot book was invented by Leslie Allard, a prominent high school band instructor and all-star percussionist. The name is derived from the use of dots on drill sheets which symbolize players on the field: a dot book focuses on the owner's particular dots and other marchers the player may have to guide (use to determine an adjusted location).

Contents

The general layout of a dot book contains the "longitudes" and "latitudes" of an American football field. However, a cartesian coordinate system (x/y) is rarely used, rather an alternative system of plotting players as dots on a grid and some jargon is used. For instance, a player may write: "3 inside 45R and 5 in front BH." This would mean that the player is 3 steps inside (towards the 50 yard line) from the 45th yard line from the right side (facing the press box) and is five steps in front of the back hash (see Field and players of American football for an explanation of terms).

Many times, however, a person's own dot book will contain their own specialized shorthand to represent their location on the field. Dot books can vary from simple (providing only the location of the marcher) to complex (also providing the location of nearby marchers whom you are guiding). This poses problems when players are switched between positions on the field: switching dot books is often difficult and many times players end up rewriting their dot books.

Dot books are considered essential by many high school band instructors to the progress of drill.

From drill sheet to dot book

This is a sample page of a pack of drill sheets. The owner of this page is AS10, and their dot on the field has been circled accordingly. After looking at this page, AS10 wrote in their page on the dot book at the top of this article. Several notable features:

Coordinate Sheets

An alternative to the dot book is the coordinate sheet. Like dot books, coordinate sheets are small and meant to be worn around the neck on a lanyard. Coordinate sheets are set up as a list of the member's places on the field, given in coordinates (such as 5 steps inside the right 45 yard line and 2.25 steps in front of the Home hash), each "set" numbered. Also on the sheet is the number of steps it takes to go from one set to another, but this isn't written plainly. Set 1 always has a "0" by it. If it should take sixteen counts to move to the next set, a "16" will be placed next to Set 2's coordinates. If it should take eight counts to move to the third set, a "24" is next to Set 3's coordinates.

A book is a medium for recording information in the form of writing or images. Books are typically composed of many pages, bound together and protected by a cover. Modern bound books were preceded by many other written mediums, such as the codex and the scroll. The book publishing process is the series of steps involved in their creation and dissemination.

<span class="mw-page-title-main">Marching band</span> Company of instrumental musicians

A marching band is a group of instrumental musicians who perform while marching, often for entertainment or competition. They are most popular in the United States, though not uncommon in other parts of the world. Instrumentation typically includes brass, woodwind, and percussion instruments. Most marching bands wear a uniform, often of a military style, that includes an associated organization's colors, name or symbol. Most high school marching bands, and some college marching bands, are accompanied by a color guard, a group of performers who add a visual interpretation to the music through the use of props, most often flags, rifles, and sabers.

A cornerback (CB) is a member of the defensive backfield or secondary in gridiron football. Cornerbacks cover receivers most of the time, but also blitz and defend against such offensive running plays as sweeps and reverses. They create turnovers through hard tackles, interceptions, and deflecting forward passes.

Marching refers to the organized, uniformed, steady walking forward in either rhythmic or route-step time; and, typically, it refers to overland movements on foot of military troops and units under field orders. Marching is often performed to march music and is typically associated with military and civilian ceremonial parades. It is a major part of military basic training in most countries and usually involves a system of drill commands.

Polocrosse is a team sport that is a combination of polo and lacrosse. It is played outside, on a field, on horseback. Each rider uses a cane or fibreglass stick to which is attached a racquet head with a loose, thread net, in which the ball is carried. The ball is made of sponge rubber and is approximately four inches across. The objective is to score goals by throwing the ball between the opposing team's goal posts.

<span class="mw-page-title-main">Drum major (marching band)</span> Military musician

A drum major or field commander is the leader of a marching band, drum and bugle corps, or pipe band, usually positioned at the head of the band or corps. The drum major is often dressed in more ornate clothing than the rest of the band or corps and is responsible for providing commands to the ensemble, leading them while marching, and directing them what to play, when to play, the dynamic or volume of playing, and what time to keep. The commands may be given verbally, through hand gestures, using a whistle or a baton, or with a mace. Although the drum major is the one conducting for the entire band to see and watch to keep time, the drum major is actually looking at the center snare's feet to keep time. The center snare is the leader of the drumline, and is the one who keeps the band in time while marching. They usually play, tap and/or rolls to set the tempo of how fast the band marches.

Glide step is a form of movement used by marching bands to minimize upper body movement, enabling musicians to play their instruments and march without air-stream interruptions. Standardizing the style of marching also serves to add to the visual effect of a marching band. Sometimes special shoes are worn with a curved heel that facilitates rolling the foot. Glide stepping is used by many high school marching bands, college marching bands, and by many Drum Corps. Glide stepping is sometimes also known as "roll stepping".

In geometry, a three-dimensional space is a mathematical space in which three values (coordinates) are required to determine the position of a point. Most commonly, it is the three-dimensional Euclidean space, that is, the Euclidean space of dimension three, which models physical space. More general three-dimensional spaces are called 3-manifolds. The term may also refer colloquially to a subset of space, a three-dimensional region, a solid figure.

In sports, a hash mark or hash line is a short line/bar marking that is painted perpendicular to the sidelines or side barricades, used to help referees and players recognize on-field locations and visually measure distances.

In physics, the relativity of simultaneity is the concept that distant simultaneity – whether two spatially separated events occur at the same time – is not absolute, but depends on the observer's reference frame. This possibility was raised by mathematician Henri Poincaré in 1900, and thereafter became a central idea in the special theory of relativity.

<span class="mw-page-title-main">American football field</span> Type of sports field

The rectangular field of play used for American football games measures 100 yards (91.44 m) long between the goal lines, and 160 feet (48.8 m) wide. The field may be made of grass or artificial turf. In addition, there are end zones extending another 10 yards (9.144 m) past the goal lines to the "end lines", for a total length of 120 yards (109.7 m). When the "football field" is used as unit of measurement, it is usually understood to mean 100 yards (91.44 m), although technically the full length of the official field, including the end zones, is 120 yards (109.7 m). The total area of the field is 57,600 sq ft or 5,350 m2. There is a goal centered on each end line, with a crossbar 10 feet (3.0 m) above the ground and goalposts 18 feet 6 inches (5.64 m) apart extending at least 35 feet (11 m) above the crossbar. Between the goal lines, additional lines span the width of the field at 5-yard intervals. This appearance led to the use of the term gridiron in the 1880s. For a few years in the early 20th century, lines perpendicular to the lines at 5-yard intervals spanned the length of the field, giving it a checkerboard-like appearance.
