Contemporary folk music refers to a wide variety of genres that emerged in the mid 20th century and afterwards which were associated with traditional folk music.
 Starting in the mid-20th century a new form of popular folk music evolved from traditional folk music.
 This process and period is called the (second) folk revival and reached a zenith in the 1960s.
 The most common name for this new form of music is also "folk music", but is often called "contemporary folk music" or "folk revival music" to make the distinction.
 The transition was somewhat centered in the US and is also called the American folk music revival.
 Fusion genres such as folk rock, folktronica, and others also evolved within this phenomenon.
 While contemporary folk music is a genre generally distinct from traditional folk music, it often shares the same English name, performers and venues as traditional folk music; even individual songs may be a blend of the two.
Jean Ritchie (December 8, 1922 – June 1, 2015) was an American folk music singer, songwriter, and Appalachian dulcimer player.
 Her career formed a kind of bridge between the traditional and modern forms of folk music: in her youth she learned folksongs in the traditional way (orally, from her family and members of her community); and in adulthood she became a successful modern folksinger, promulgating songs in public through concerts and recordings.
 She was called by some the "Mother of Folk".
Andrew Rowan Summers (December 15, 1912– March 1968) was an American folk singer and player of the Appalachian dulcimer.
 He is credited with a large role in preserving Appalachian music from extinction.
 Summers was among the earliest musicians to draw attention to the dulcimer to a wider audience outside the Appalachians, with John Jacob Niles being one of the few earlier.
Kevin Roth (born 1957 in Philadelphia, Pennsylvania) is an American folk singer and Appalachian dulcimer player who has released forty-five albums.
Stephen Seifert (born September 29, 1973) is an American folk musician and virtuoso of the Appalachian dulcimer.
 He has released many educational DVDs and videos on the subject of dulcimer playing.
David Massengill (born 1951, Bristol, Tennessee) is an American folk singer-songwriter, guitar and appalachian dulcimer player.
 His best-known songs include: "On The Road to Fairfax County", recorded by The Roches and by Joan Baez; "The Great American Dream"; and "My Name Joe", about an illegal immigrant restaurant worker.
 For some years after he began recording, Massengill maintained a day job as a restaurant dishwasher.
 He also contributed his poignant dulcimer-centered version of "The Crucifixion" to 2001's multi-artist double-disc tribute to Phil Ochs, "What's That I Hear".
Joemy Wilson is a hammered dulcimer player from New Haven, Connecticut.
 Her first instruments were the piano and violin.
 She also took voice lessons in high school.
 She started playing Appalachian dulcimer while attending Barnard College, and started playing hammered dulcimer in 1979.
"Brightest and Best" (occasionally rendered by its first line, "Brightest and Best of the Sons of the Morning") is a Christian hymn written in 1811 by the Anglican bishop Reginald Heber to be sung at the feast of Epiphany.
 It appeared in Heber's widow's compilation of hymns entitled "Hymns Written and Adapted to the Weekly Service of the Church Year" in 1827.
 It can be sung to a number of tunes, including "Morning Star" by James P. Harding, "Epiphany" by Joseph Thrupp, and "Star in the East" by William Walker.
 It appears in "The Lutheran Hymnal", and appeared in the 1966 Methodist hymnal.
 It has been recorded by a number of artists, including Glen Campbell, Joanne Hogg and Kathy Mattea (on her album "Good News").
 The Kentucky traditional singer Jean Ritchie often sang this and told of her childhood memory of her grandmother sitting by the fire and singing it quietly to herself on Twelfth Night; the Library of Congress collected it from her in 1951.
