#rhythmic structure
- Amphibrachic — Belonging to the amphibrach, relating to the amphibrach, or composed of amphibrachs; a rhythm, verse, or metrical system based on the utilization of three-syllable feet with the stress structurally placed on the second syllable.
- Anacrusia — The character or state of a composition, verse, or rhythmic phrase that structurally begins with an anacrusis; the formal property of a metrical or melodic system to place unaccented elements (pickup notes or atonic syllables) before the first downbeat or ictus. This aesthetic phenomenon dictates a more fluid flow and a progressive launch of the general rhythm.
