The DeGarmo Intro to Music Braille Transcription 2005 is out of date. It is currently being revised to reflect UEB and the Music Braille Code 2015 updates. Hopefully the revised edition will be available soon!
In the meantime, it's helpful to have the Music Braille Code 2015 by your side to look up things like this.
We use UEB italics where they are needed, not EBAE.
Parentheses - there are three types we use in braille music. (See MBC2015 section 1.3.) UEB literary in ordinary literary context; Music parentheses (dots 6,3) in the music. Special parentheses (dots 2356) for chord symbols, music headings, and in word-sign expressions.
In the case of numbering vocal music verses, we use UEB parentheses. (See MBC2015 section 35.7.)
