trillingsmodi

Trillingsmodi is a term used in music theory and performance practice to describe a family of ornamentation techniques that realize a trill in melodic lines. The concept defines several modes, each with characteristic starting pitch, rhythm, and termination, to guide stylistic realization.

Etymology and scope: The word combines trill with modi (modes) from Nordic and Latin sources, and has appeared in musicological writings since the 19th century as a framework for analyzing ornaments across Baroque, Classical, and folk-influenced repertoires.

Classification: Typical modes cover variations in start and duration. Modus primus begins on the upper neighbor with fast, even alternation and a short termination. Modus secundus starts on the lower neighbor and often yields a broader, slower trill. Modus punctatus is a brief, punctuated form suited to brisk tempos. Modus longus extends the trill, allowing a flexible ending in expressive passages.

Notation and performance: Trillingsmodi are usually indicated by standard trill signs, with editorial or performer cues specifying the intended mode. In historically informed practice, choices reflect source material, period conventions, and instrument-specific feasibility.

Relation to other ornaments: Trillingsmodi relate to mordents, turns, and appoggiaturas, sharing concerns about pitch adjacency, timing, and cadence, and providing a structured vocabulary for interpreting trill realizations. See also: Trill (music), Mordent, Turn (music), Ornament (music).
