The vowel keyword indicates that the characters which follow, until the next semicolon, should be considered vowels. There may be multiple vowel statements, and the characters following all of them will be considered vowels.
These strings follow the keyword and must be separated by space and end with a semicolon. There may be multiple prefix statements, and all will apply. Examples of prefixes include "i" and "u" in Latin and "qu" in English.
The suffix keyword lists strings of characters which don't start with a vowel, but when appearing after a sequence of vowels, SHOULD be considered part of the vowel sound. There may be multiple suffix statements, and all will apply. Examples of suffixes include "w" and "we" in English and "y" in Spanish. The secondary keyword lists strings of characters which do not contain vowels, but for which, when there are no vowels present in a syllable, define the center of the syllable.
Examples of secondary sequences include "w" from Welsh loanwords in English and the syllabic consonants "l" and "r" in Czech. Gregorio comes with a gregorio-vowels. The available aliases for the Slavic languages are:. For other languages or to modify the rules for Latin, English, or the Slavic languages , you will have to write your own gregorio-vowels. If you do write vowel definitions for a new language, you are invited to submit them for inclusion in future versions of Gregorio. See the the contributing guide for details.
Additionally, if it is necessary, it is possible to control the portion of a particular syllable which is identified as the vowel. To do this, put the part of the text to be considered the vowel between braces in the gabc. For instance, in the following example the neumes will align with the center of "ve" instead of the first "e":. Finally, Gregorio T e X provides two alternate rule sets which don't rely on vowel identification: centering the whole syllable under the first neume and centering the first letter of the syllable under the first neume.
The initial is automatically recognized by gregorio as the first letter. Setting this value to 0 means that the initial will not be separated out and will appear with the rest of its syllable under its notes. Note that in the case of a syllable composed of one letter only, Gregorio T e X automatically adds a hyphen under the first notes.
It can happen that the texts of Gregorian chants contain unicode characters which are not easily accesible from the keyboard. There is also the possibility of a non-unicode character such as the barred A for Antiphon. Gregorio will allow the use of any unicode character directly entered via your platform's character picker or a keyboard shortcut.

Correspondence between letter and staff position. The different shapes. Example of complex neume. For hymns, it is useful to repeat the melody over each verse. It is also useful to have sections of melody and text, each of which repeats the melody for that section over all the text, for example with a hymn that has several verses followed by an "amen" of an entirely different melody.
This can be done by separating the sections with a line that consists entirely of two dashes: "--", or 1. It will not repeat the GABC for the last section, so if you have only one section and want it to repeat over all the text, you will have to enter the last line as This is where certain aspects of the textual part of the output can be adjusted.
Otherwise, all but the first and sometimes second verse will be formatted text with no GABC. Also, you can adjust the settings for the first verse by selecting GABC and changing the settings on the right side, and then selecting the format that you actually want to use for the subsequent verses.
The parameters of the currently selected verse format show up on the right, "Begin Preparatory Syllable", etc. The default format is to italicize the preparatory syllables and to bold the accented syllables.
The non-breaking space is used between a word and a flex or mediant to prevent a line break from occurring. The "Verses Filename" is used when dragging the 'Download Verses' link from Chrome no other browsers support this into an Explorer window as the name of the file. It is also used by the "Download ZIP of all psalms in each tone" for the name of the verses files. It is also applied to the name field in the header, but for this it will cut off everything after the last period as well as the period itself e.
This is three separate tools to aid in the transcription of chant into GABC notation, and a fourth which only deals with chants that have already been transcribed. The others are the " Readings Tool " and the " Propers Tool ". My name is Benjamin Bloomfield, and the schola that I sing with in Cincinnati, Ohio began chanting Vespers every Sunday in Lent of , but not all of us have a Liber Usualis to sing from, so we were making copies of the chant and pointed psalms from the Liber Usualis every week.
I thought about retypesetting things with Gregorio and TeX , but one of the problems was that formatting the text of the psalms with certain syllables in bold and italic is both tedious and error-prone when done by hand.
While chanting Vespers one Sunday in January , I realized that it would be relatively simple to write a computer program to automatically break apart a Latin text into syllables, and as long as the accents are already marked apply a psalm tone to it or mark certain syllables as bold or italic.
In the process of writing this Psalm Tone Tool, it became obvious that it would also be advantageous to split apart Latin into its syllables simply to prevent having to type so many parentheses, and thus the GABC Transcription Tool was born. I put together the Readings Tool after my dad a permanent deacon had asked about chanting a specific Gospel in English. The Propers Tool, I wrote more recently in at the suggestion of one of my brothers. I had begun a project in May , thinking it would be simple to render GABC into a webpage, but abandoned it later in the year, half-finished.
When I wrote these tools, it was a natural fit to use what I already had half-working in order to allow for a graphical preview of the chant, and actually using this code for something provided additional inspiration for getting it to work better, because it is annoying whenever it displays something incorrectly, and thus I have improved much in the rendering of the chant preview since writing the transcription tool.
Some of the tools use the Exsurge library by Father Matthew Spencer. It is hosted at Github, here. One or two of them may have been asked by a real person, but certainly not frequently. You can get the Chrome Web App version here and it will work whether you are connected to the Internet or not, and there is an Android App available here.
Would you like any of my money as a way of thanking you for putting these tools together? Not really, but if you insist, you can send me a donation. What about for the iPhone version? Doesn't Apple charge you to join their developer program?

In the Solesmes hymnary of , two new notations were introduced: the pesquassus and the podatus initio debilis. The first is written using an o after the first note, as it is an oriscus , and the second is written logically with a - before the first note. A new written form of the podatus is also proposed here.
It could be used to distinguish pes quadratus of the old notation that is currently transcribed in the same way that the light pes and the pes with episema are.
In this new written form of the podatus, the second note is located to the right of the bar that links the two notes, and not to the left. These pes quadratus are notated by adding a q between the two notes. As the empty notes and accents are quite rare, the notation to get them is not very intuitive, but is still simple: simply add the following signs after your note:.
The goal of the notation presented here is to represent Gregorian chant, and thus songs in only one voice. However, the first polyphonic pieces were written in square notation, even if the current notation is slightly different, so it seemed important to consider the case of people who would want to write polyphonic scores in square notation. Sadly the typography of polyphony on several levels of staffs is way more difficult than the normal typography, and it's not yet possible with Gregorio or any other serious gregorian software of which we are aware.
Gregorio does support a simple notation for simple polyphony on one staff line. This is possible in gabc when putting the first note of a vertically aligned group between curly brackets:.
As a result of the difficulty in rendering polyphony typographically, there are a few quirks with the above notation that users should be aware of:. Since polyphony is so rare in Gregorian chant, improving the behavior of Gregorio in this area is extremely low on the list of priorities for the developers.
If you find yourself using this feature and want improvements, then you are most likely going to have to make them yourself see the contributing guide for how to get started. The end of line is automatically determined by the Gregorio T e X. However, under some circumstances it can be useful for you to specify it because it improves the rendering. To force an end of line at the end of a syllable put z inside parentheses after the notes.
If you want your line to end without being justified, use Z instead. By default the custos an indication of the first note on the next line is automatically generated at each line ending within a score, whether that line ending be automatic or manually determined.
Further, the behavior at a manual line break z or Z can be specified on a case-by-case basis. In some cases, it may be necessary to typeset a custos inside a line. This is the case of a clef change, for example. In this particular case, simply type z0 before the clef change to get it; its height will be calculated automatically. To add a translation or a second line of text , simply put it between square brackets in the syllable text.
In either case, the translation won't go to the next line automatically. Thus it may require a bit of work to get the desired effect. It is also possible to span the centering of a translation over several syllables. If you do this, the multi-syllable translation will be centered over the span of syllables regardless of the setting for translation centering for an individual syllable. This text will be left-aligned with the first note of the syllable.
It is also possible to typeset text entering [alt:my text] in the notes, which will align "my text" with the next note. It is possible to produce choral signs in gabc.
