Country music often consists of ballads and dance tunes with generally simple forms, folk lyrics, and harmonies mostly accompanied by string instruments such as banjos, electric and acoustic guitars, steel guitars (such as pedal steels and dobros), and fiddles as well as harmonicas. Blues modes have been used extensively throughout its recorded history.
Pioneers of a more Americanised popular country music in Australia included Tex Morton (known as "The Father of Australian Country Music") in the 1930s. Author Andrew Smith delivers a through research and engaged view of Tex Morton's life and his impact on the country music scene in Australia in the 1930s and 1940s. Other early stars included Buddy Williams, Shirley Thoms and Smoky Dawson. Buddy Williams (1918–1986) was the first Australian-born to record country music in Australia in the late 1930s and was the pioneer of a distinctly Australian style of country music called the bush ballad that others such as Slim Dusty would make popular in later years. During the Second World War, many of Buddy Williams recording sessions were done whilst on leave from the Army. At the end of the war, Williams would go on to operate some of the largest travelling tent rodeo shows Australia has ever seen.
Country music was aided by the U.S. Federal Communications Commission's (FCC) Docket 80–90, which led to a significant expansion of FM radio in the 1980s by adding numerous higher-fidelity FM signals to rural and suburban areas. At this point, country music was mainly heard on rural AM radio stations; the expansion of FM was particularly helpful to country music, which migrated to FM from the AM band as AM became overcome by talk radio (the country music stations that stayed on AM developed the classic country format for the AM audience). At the same time, beautiful music stations already in rural areas began abandoning the format (leading to its effective demise) to adopt country music as well. This wider availability of country music led to producers seeking to polish their product for a wider audience. In 1990, Billboard, which had published a country music chart since the 1940s, changed the methodology it used to compile the chart: singles sales were removed from the methodology, and only airplay on country radio determined a song's place on the chart. https://www.youtube.com/channel/UCfRkrq7xfAiSbWaIKJ2vSHg
Vernon Dalhart was the first country singer to have a nationwide hit in May 1924 with "Wreck of the Old 97". The flip side of the record was "Lonesome Road Blues", which also became very popular. In April 1924, "Aunt" Samantha Bumgarner and Eva Davis became the first female musicians to record and release country songs. Many "hillbilly" musicians, such as Cliff Carlisle, recorded blues songs throughout the decade and into the 1930s. Other important early recording artists were Riley Puckett, Don Richardson, Fiddlin' John Carson, Uncle Dave Macon, Al Hopkins, Ernest V. Stoneman, Blind Alfred Reed, Charlie Poole and the North Carolina Ramblers and The Skillet Lickers. The steel guitar entered country music as early as 1922, when Jimmie Tarlton met famed Hawaiian guitarist Frank Ferera on the West Coast.
By the end of World War II, "mountaineer" string band music known as bluegrass had emerged when Bill Monroe joined with Lester Flatt and Earl Scruggs, introduced by Roy Acuff at the Grand Ole Opry. That was the ordination of bluegrass music and how Bill Monroe became to be known as the "Father of Country Music." Gospel music, too, remained a popular component of bluegrass and other sorts of country music. Red Foley, the biggest country star following World War II, had one of the first million-selling gospel hits ("Peace in the Valley") and also sang boogie, blues and rockabilly. In the post-war period, country music was called "folk" in the trades, and "hillbilly" within the industry. In 1944, The Billboard replaced the term "hillbilly" with "folk songs and blues," and switched to "country" or "country and Western" in 1949. https://www.youtube.com/watch?v=hyNAvdnZ5Ec
