Four general principles of hyphenating lyrics: HYPHENATE: 1) Between double-letters (fun-ny). 2) Between differing consonant sounds (cen-tral, not ce-ntral). 3) Elongate vowels (che-mi-stry); 4) Make exceptions, however, for clarity (book-ing, not boo-king). Dictionaries aren’t the authority here; your ears are.
