The Gregory Walker or passamezzo moderno ("modern half step"; also quadran, quadrant, or quadro pavan) was "one of the most popular harmonic formulae in the Renaissance period, divid[ing] into two complementary strains thus:"
- (Middleton 1990, 117).
For example, in C major the progression is as follows:
C F C G C F C-G C
The progression or ground bass, the major mode variation of the passamezzo antico, originated in Italian and French dance music during the first half of the 16th century, where it was often used with a contrasting progression or section known as ripresi. Though one of Thomas Morley's characters in Plaine and Easie Introduction to Practicall Musicke denigrates the Gregory Walker, comparing unskilled singing to its sound (Morley 1597, 120), it was popular in both pop/popular/folk and classical musics through 1700. Its popularity was revived in the mid 19th century, and the American variant (below) evolved into the twelve bar blues (van der Merwe 1989, 198–201).
Listed in van der Merwe (1989, 198–201):
- several in The Fitzwilliam Virginal Book
- "Up and Ware Them A Willie"
- "Jimmie Rose"
- "Darling Nelly Gray" Play (help·info)
- "Wreck of the Old 97"
- Woody Guthrie's "There is a House in This Old Town"
- Irving Berlin's "Alexander's Ragtime Band"
- The Rolling Stones' "Honky Tonk Women" (1969)
- Carole King's "You've Got a Friend" (1971)
- Hans Neusidler's "Gassenhawer" (Nuremberg, 1536)
- "Oxstedter Mühle" (folk dance from Lower Saxony) (B section)
- Diego Ortiz' Recercada Prima / Segunda / Tercera sobre el Passamezzo Moderno (three-part didactic composition in Tratado de Glosas sobre cláusulas y Otros Generos de Puntos en la Música de Violones, 1553). (Readers of Spanish may benefit from the Spanish-language Wikipedia's more extensive treatment of Diego Ortiz and of the Tratado de Glosas.)
- Iron & Wine's "A History of Lovers" (Iron e Wine 2005,[page needed]) (verses; chorus and interludes follow ripresi IV-I-IV-V progression)
American Gregory Walker
- (Middleton 1990, 117).
For example, in C major this variation is as follows:
C F-C C G C F-C C-G C
Listed in van der Merwe (1989, 201–202):
- "Jesse James"
- "The Titanic"
- "My Little Old Sod Shanty"
- Gus Cannon's "Walk Right In" (1929)
On original progression
- Second strain's first I becomes I-I7 (for a stronger "lead-in" to the upcoming IV):
- "Gathering Flowers From the Hillside" (Carter Family 1935)
- Second strain progresses from IV directly to a full measure of V, displacing its second (half-measure) I:
- Bluegrass variation: First strain's change from I to IV and back is omitted:
- "She'll Be Comin' 'Round the Mountain" (traditional) text at Anon [n.d.]; melody at http://www.ingeb.org/songs/cominrou.mid (file composed specifically for dissemination via ingeb.org website pursuant to site's policy imposing non-commercial and share-alike restrictions but not attribution requirement)
- The Bluegrass variation frequently occurs in conjunction with the I-I7 "lead-in" and/or the direct IV-to-V transition listed above.
The resulting progression is ||| I | I | I | V || I(-I7) | IV | (I-)V | I ||| ; examples include:
On American variant
- IV-I is reversed, becoming I-IV or I7-IV:
- Second I in second strain becomes II7, yielding second-strain progression of || I | IV-II7 | I-V | I ||| :
- Caution: Keeping all chords in root position produces parallel fifths (see parallel harmony), which are prohibited by classical (rather than popular) voice-leading rules. The following files may or may not be more suitable for use in strict counterpoint: progression with tonic (I) chord in root position (help·info), tonic in first inversion (help·info), tonic in second inversion (help·info); though they lack the ground bass.
