Final answer:
The composers Pérotin and Léonin should be arranged in chronological order, with Léonin coming before Pérotin based on their associations with the Notre Dame school of polyphony. John of Forneste is not a recognized figure in music history and is assumed to come after Pérotin.
Step-by-step explanation:
The question asked pertains to the chronological order of three specific composers named: A) Pérotin, B) Léonin, and C) John of Forneste. Although there might be a typo or unfamiliar name, we can provide information on the two recognized composers, Pérotin and Léonin.
Both were notable figures in the Notre Dame school of polyphony which flourished in the 12th and early 13th centuries. Léonin is often credited as one of the earliest known composers of polyphonic music, working mainly in the second half of the 12th century. Following him chronologically is Pérotin, who succeeded Léonin and moved the style forward in the late 12th and early 13th centuries. As for the composer identified as John of Forneste, there is less certainty, as he is not a well-known historical figure within the field of music history.
The task is to arrange these composers from earliest to latest. Based on available historical data, the correct chronological order would be:
- Léonin
- Pérotin
- John of Forneste (assuming he falls chronologically after Pérotin)
the sequence from earliest to latest of the given composers is: Léonin, Pérotin, followed by John of Forneste.
