bluegrass music

Bluegrass music is a genre of American roots music that developed in the 1940s in the Appalachian region of the United States. The genre derives its name from the band Bill Monroe and the Blue Grass Boys. Like mainstream country music, it largely developed out of old-time string music, though in contrast, bluegrass is traditionally played exclusively on acoustic instruments and also has roots in traditional English, Scottish, and Irish ballads and dance tunes as well as in blues and jazz. Bluegrass was further developed by musicians who played with Monroe, including 5-string banjo player Earl Scruggs and guitarist Lester Flatt. Monroe characterized the genre as: "Scottish bagpipes and ole-time fiddlin'. It's a part of Methodist, Holiness and Baptist traditions. It's blues and jazz, and it has a high lonesome sound."

Bluegrass features acoustic stringed instruments and emphasizes the off-beat. Notes are anticipated, in contrast to laid back blues where notes are behind the beat, which creates the higher energy characteristic of bluegrass. In bluegrass, as in some forms of jazz, one or more instruments each takes its turn playing the melody and improvising around it, while the others perform accompaniment; this is especially typified in tunes called breakdowns. This is in contrast to old-time music, in which all instruments play the melody together or one instrument carries the lead throughout while the others provide accompaniment. Breakdowns are often characterized by rapid tempos and unusual instrumental dexterity and sometimes by complex chord changes.

Characteristics

Instrumentation

The violin (also known as the fiddle), five-string banjo, guitar, mandolin, and upright bass (string bass) are often joined by the resonator guitar (also referred to as a Dobro) and (occasionally) harmonica or Jew's harp. This instrumentation originated in rural dance bands and is the basis on which the earliest bluegrass bands were formed.

The fiddle, made by Italians and first used in sixteenth century Europe, was one of the first instruments to be brought into America. It became popular due to its small size and versatility. Fiddles are also used in country, classical, and old time music.

Banjos were brought to America through the African slave trade. They began receiving attention from white Americans when minstrel shows incorporated the banjo as part of their acts. The " clawhammer", or two finger style playing, was popular before the Civil War. Now, however, banjo players use mainly the three-finger picking style made popular by banjoists such as Earl Scruggs.

Guitarists have an important role in bluegrass. They are used primarily for rhythmic purposes and keep the sound moving while other instruments take time for a break as well as taking breaks themselves on occasion. The instrument originates from eighteenth century Spain, but there were no American-made models until the C.F. Martin Company started to manufacture them in the 1830s. The guitar is now most commonly played with a style referred to as flatpicking, unlike the style of early bluegrass guitarists such as Lester Flatt, who used a thumb pick and finger pick.

Bassists almost always play pizzicato, occasionally adopting the "slap-style" to accentuate the beat. A bluegrass bass line is generally a rhythmic alternation between the root and fifth of each chord, with occasional walking bass excursions.

Instrumentation has been a continuing topic of debate. Traditional bluegrass performers believe the "correct" instrumentation is that used by Bill Monroe's band, the Blue Grass Boys (guitar, mandolin, fiddle, banjo, and bass). Departures from the traditional instrumentation have included dobro, accordion, harmonica, piano, autoharp, drums, electric guitar, and electric versions of other common bluegrass instruments, resulting in what has been referred to as "new grass", although even Monroe himself was known to experiment with instrumentation, once even using a string orchestra, choir, and pre-recorded bird-song track.

Vocals

Apart from specific instrumentation, a distinguishing characteristic of bluegrass is vocal harmony featuring two, three, or four parts, often with a dissonant or modal sound in the highest voice (see modal frame), a style described as the "high, lonesome sound." Commonly, the ordering and layering of vocal harmony is called the "stack". A standard stack has a baritone voice at the bottom, the lead in the middle (singing the main melody) and a tenor at the top; although stacks can be altered, especially where a female voice is included. Alison Krauss and Union Station provide a good example of a different harmony stack with a baritone and tenor with a high lead, an octave above the standard melody line, sung by the female vocalist. However, by employing variants to the standard trio vocal arrangement, they were simply following a pattern existing since the early days of the genre. Both the Stanley Brothers and the Osborne Brothers employed the use of a high lead with the tenor and baritone below it. The Stanleys used it numerous times in their recordings for both Mercury and King records. This particular stack was most famously employed by the Osborne Brothers who first employed it during their time with MGM records in the latter half of the 1950s. This vocal arrangement would become the trademark of the Osbornes' sound with Bobby's high, clear voice at the top of the vocal stack. Additionally, the Stanley Brothers also utilized a high baritone part on several of their trios recorded for Columbia records during their time with that label (1949–1952). Mandolin player Pee Wee Lambert sang the high baritone above Ralph Stanley's tenor, both parts above Carter's lead vocal. This trio vocal arrangement was variously used by other groups as well; even Bill Monroe employed it in his 1950 recording of "When the Golden Leaves Begin to Fall'. In the 1960s Flatt and Scruggs often added a fifth part to the traditional quartet parts on gospel songs, the extra part being a high baritone (doubling the baritone part sung in the normal range of that voice; E.P. Tullock ka Cousin Jakenormally providing the part, though at times it was handled by Curly Seckler).

Themes

Bluegrass tunes often take the form of narratives on the everyday lives of the people whence the music came. Aside from laments about loves lost, interpersonal tensions and unwanted changes to the region (e.g., the visible effects of mountaintop coal mining</
