A quick alternation of a principal tone with the tone above

"Pralltriller" is a musical term derived from German, used to describe a specific ornamental technique or trill technique, also known as "Prall trill" or "Turn". This technique is characterized by the rapid alternation between the indicated note and the note immediately above it, frequently accompanied by a swift auxiliary note played before the primary note.

The symbol representing pralltriller bears resemblance to a lowercase letter "m" or a squiggly line and serves to introduce ornamentation and embellishment into the musical composition. The execution of a pralltriller may exhibit variation, contingent upon the musical style and interpretational nuances, but it consistently entails the swift and controlled oscillation of the specified note.

The pralltriller is prominently featured in music from the Baroque, Classical, and Romantic eras, frequently adorning melodic lines, cadences, or technically demanding passages. Proficiency in performing a pralltriller necessitates adept finger dexterity, precise coordination, and a keen sensitivity to musical expression.
