Byzantine Chant Notation
• Liturgical chant of Greek Orthodox Church

• Current use is uncommon
• monophonic

Byzantine Chant Notation
• 72 notes in octave• Symbols indicate:
– Relative pitch change– Manner in which note is sung– Duration of note
• One of several modes and a start note picked initially• Microtonal variations important

• Lines and curves written above text
• Indicates rough melodic shape
• Memory aid to singers

Gregorian Chant
• Developed by Guido d’ Arezzo (990-1150)
• Staff + clef indicates pitch
Monophonic•More verbose, but more precise

Modern Notation
• Evolved from Gregorian chant
• Essentially unchanged since 17th century
• Evolved `organically’
• Symbolic graphical language
