E, fifth letter of the alphabet. It is a usual symbol for a mid-front vowel, such as ĕ in the English step. A mid-front vowel was represented by Greek epsilon [Gr., = e without the aspirate], to which E corresponds in form and place (see also H). English ē is pronounced as a diphthong of ĭ and y. In musical notation E represents a note in the scale.
