# The Virgapes System

The virgapes system assigns a unique identifier to every type of neume listed in Cardine's guide to neumes. With a four-part identifier, we can distinguish the number of pitches in the neume, the relative motion of the pitches, the presence and location of an episema, and the presence of a liquescent form. Each part is signified with a number and each part is separated by a period.

For example, a virga would be encoded as 1.1.0.0, to indicate that it has one pitch, is the first (of two) one-pitch neumes, and has no episema or liquescence. A liquescent virga would be encoded as 1.1.0.1. A virga with an episema would be encoded as 1.1.1.0.

# Language of Neume encoding

(pitch).(id_number).(episema).(liquescence)

## Pitch

number of pitches in neume

• Punctum, for example, has one pitch, and is encoded as '1'
• Roman characters are encoded with '0' for 0 pitches

## Id Number

distinguisher between neumes with the same pitches

• Beginning with '1'
• Punctum (1.1.0.0) vs. virga (1.2.0.0), for example, are '1' and '2'

## Episema

notes whether a neume has episema, and if so, on which pitch

• '0' = no episema
• '1' = episema marked on first pitch
• '2' = episema marked on second pitch
• etc.

## Liquescence

notes whether a neume has liquescence or not

• '0' = no liquescence
• '1' = liquescence marked on first pitch
• '2' = liquescence marked on second pitch
• etc.

# Standards for entering neumes

[WIP]

• When encoding neumes, a space " " stands for separation between syllables and "-" connects neumes within a single syllable. A new line indicates a new word.
• Work left to right one syllable at a time
• If a significative letter is directly above a neume then work from top to bottom
• Assume that neumes proceed in one continuous line, breaking when the scribe runs out of room

# URN system

### Occasion

• urn:cts:chant:(type-of-chant-book).(manuscript).(feast-day).(chant)

### Text/Neumes

• urn:cts:chant:(type-of-chant-book).(manuscript).(cantus_id).(text/neume)

urn:cts:chant:antiphonary.einsiedeln121.cantus.text

urn:cts:chant:antiphonary.einsiedeln121.cantus.neume

# Encoding Rules

• "unclear" = mark unclear passages
• "wip" = mark items to return to, should not appear in finished versions

# Standard Alphabet

• Set of letters: A B C D E F G H I L M N O P Q R S T U X
• Uses "u" not "v"; "i" not "j"
• Updated as needed
