Is there a specific way in which to identify euphony?
Euphony is melodious and pleasing.
Euphony is achieved through the use of vowel sounds in words of generally serene imagery. Vowel sounds, which are more easily pronounced than consonants, are more euphonious; the longer vowels are the most melodious. Liquid and nasal consonants and the semivowel sounds (l, m, n, r, y, w) are also considered to be euphonious.
