"Bugle Call Rag" is a jazz standard written by Jack Pettis, Billy Meyers and Elmer Schoebel. It was first recorded by the New Orleans Rhythm Kings in 1922 as "Bugle Call Blues", although later renditions as well as the published sheet music and the song's copyright all used the title "Bugle Call Rag". The song was popularized as a standard by swing era renditions by Benny Goodman and Glenn Miller.

The song appears in several Hollywood films, including Orchestra Wives (1942), Stage Door Canteen (1943), The Benny Goodman Story (1956) and The Aviator (2004).

A bugle call is a short tune, originating as a military signal announcing scheduled and certain non-scheduled events on a military installation, battlefield, or ship. Historically, bugles, drums, and other loud musical instruments were used for clear communication in the noise and confusion of a battlefield. Naval bugle calls were also used to command the crew of many warships (signaling between ships being by way of signal flags.)

A defining feature of a bugle call is that it consists only of notes from a single overtone series. This is in fact a requirement if it is to be playable on a bugle or equivalently on a trumpet without moving the valves. (If a bandsman plays calls on a trumpet, for example, one particular key may be favored or even prescribed, such as: all calls to be played with the first valve down.)

Bugle calls typically indicated the change in daily routines of camp. Every duty around camp had its own bugle call, and since cavalry had horses to look after, they heard twice as many signals as regular infantry. "Boots and Saddles" was the most imperative of these signals and could be sounded without warning at any time of day or night, signaling the men to equip themselves and their mounts immediately. Bugle calls also relayed commanders' orders on the battlefield, signaling the troops to Go Forward, To the Left, To the Right, About, Rally on the Chief, Trot, Gallop, Rise up, Lay down, Commence Firing, Cease Firing, Disperse, and other specific actions.

Bernard "Buddy" Rich (September 30, 1917 – April 2, 1987) was an American jazz drummer and bandleader. Rich was billed as "the world's greatest drummer" and was known for his virtuosic technique, power, groove, and speed.

Rich was born in Brooklyn, New York, to Jewish vaudevillians Robert and Bess Rich. His talent for rhythm was first noted by his father, who saw that Buddy could keep a steady beat with spoons at the age of one. He began playing drums in vaudeville when he was 18 months old, billed as "Traps the Drum Wonder." At the peak of Rich's childhood career, he was reportedly the second-highest paid child entertainer in the world (after Jackie Coogan). At 11 he was performing as a bandleader. He received no formal drum instruction, and went so far as to claim that instruction would only degrade his musical talent. He also never admitted to practicing, claiming to play the drums only during performances^{[citation needed]} and was not known to read music. He expressed great admiration for, and was influenced by, the playing of Chick Webb, Gene Krupa, Dave Tough, and Jo Jones, among others.^{[citation needed]}.

Benjamin David “Benny” Goodman (May 30, 1909 – June 13, 1986) was an American jazz and swing musician, clarinetist and bandleader; widely known as the "King of Swing".

In the mid-1930s, Benny Goodman led one of the most popular musical groups in America. His January 16, 1938 concert at Carnegie Hall in New York City is described by critic Bruce Eder as "the single most important jazz or popular music concert in history: jazz's 'coming out' party to the world of 'respectable' music."

Goodman's bands launched the careers of many major names in jazz, and during an era of segregation, he also led one of the first well-known racially-integrated jazz groups. Goodman continued to perform to nearly the end of his life, including exploring his interest in classical music.

Goodman was born in Chicago, the ninth of twelve children of poor Jewish immigrants from the Russian Empire, who lived in the Maxwell Street neighborhood. His father was David Goodman, a tailor from Warsaw; his mother was Dora Grisinsky (from Kaunas, Lithuania). His parents met in Baltimore, Maryland, and moved to Chicago before Benny was born.

Alton Glenn Miller (March 1, 1904 – missing in action December 15, 1944) was an American jazz musician (trombone), arranger, composer, and bandleader in the swing era. He was one of the best-selling recording artists from 1939 to 1943, leading one of the best known Big Bands. Miller's notable recordings include "In the Mood", "Moonlight Serenade", "Pennsylvania 6-5000", "Chattanooga Choo Choo", "A String of Pearls", "At Last", "(I've Got a Gal In) Kalamazoo", "American Patrol", "Tuxedo Junction", and "Little Brown Jug". While he was traveling to entertain U.S. troops in France during World War II, Glenn Miller disappeared in bad weather over the English Channel. The Glenn Miller Orchestra was re-formed after the war and continues to record and perform to this day.

Miller was born on a farm in Clarinda, Iowa, to Lewis Elmer Miller and Mattie Lou (née Cavender). He went to grade school in North Platte in western Nebraska. In 1915, Miller's family moved to Grant City, Missouri. Around this time, Miller had finally made enough money from milking cows to buy his first trombone and played in the town orchestra. In 1918, the Miller family moved again, this time to Fort Morgan, Colorado, where Miller went to high school. During his senior year, Miller became very interested in a new style of music called "dance band music." He was so taken with it that he formed his own band with some classmates. By the time Miller graduated from high school in 1921, he had decided he wanted to become a professional musician.
