All the rhythmical signs are integrated into the same font and can be placed at the preferred level of the stave, and also at different horizontal positions without interfering with other substitutions. Each different schola uses his own preferred hints; in Gregoria there are: punctum-mora (obtained with

the period combined with a letter to place it on the stave; adding a number from 1 to 4 allows to specify the horizontal position); transversum episema (obtained with comma, has 4 different lenghts); vertical episema (apostrophe).

These are special neumes that have the last one or two last notes of smaller size, to put the attention on the correct pronunciation of the text. The easyest way to access this “alternates” is to select a complementary font. We used the conventional styles italic and bold to immediately

obtain the augmentative and diminutive liquescences.
This extra fonts behave in the same way than roman concerning features and exceptions.
