The declamation of the Masoretic Text likely featured a structured rhythm with breves and longs, similar to other traditions of elevated recitation. Unlike the Qur’ān recitation, this rhythm was not determined by syllable structures but by prominences linked to stress and phrasing, as indicated by Masoretic accentuation. This prosody is best seen in the recitation of the Yemenite Jews, whose tradition shares many similarities with Masoretic Hebrew. The interaction between independently determined breves and longs and long and short vowels alters vowel length; in turn, syllable structures slightly influence the duration of breves. Neither phrasing hierarchy nor melodic pitch resembles spoken prosody. Melody supports the prominence of phrasing boundaries; however, the main purpose of the melodic line is to mark the division into verses. The signs of Masoretic accentuation were only partly a direct representation of sound distinctions, and even less so of the specific melodic contours.
