Prosody
Prosody deals with the pronunciation of vowels. A vowel with an adjacent consonant make a syllable. When speaking we vary the loudness (soft and loud) and the length of a vowel.
In Ancient Greek vowels were divided into long and short, for example omicron is a short o while omega is a long o. The same word can have a different meaning if a vowel is short or long. In Modern Greek although the old spelling is retained vowels are pronounced with equal length and a word can change meaning according to which syllable is stressed.
In some languages the stressing of syllables is important, in others less so. In French the stressed syllable of a word is invariably the last one while in Italian it is the one before the last. In Modern Greek the stress can fall on one of the last three syllables of a word while very long words can have two stressed syllables. Ancient Greeks gave more importance to the length of vowels than to their loudness.
Our voice goes up and down when passing from a stressed to an unstressed vowel. We can align words in such a way that a regularity of tone is produced, thus creating a pleasant effect. This is done in poetry. Ancient Greek poetry is based on the rhythmic patterns produced by the succession of long and short vowels. These patterns are called metrical feet.
