Alternés

Alternés refers to a technique in music, particularly in classical and Baroque periods, describing a specific way of executing a passage. It involves the rapid alternation between two notes, often the main note and a neighboring note, or between the main note and its upper or lower neighbor. This creates a shimmering or trilling effect. The term is often associated with ornamental figures, where it adds brilliance and embellishment to a melodic line. While the concept is straightforward, the precise execution can vary depending on the musical context, the era, and the composer's intentions. It's a common feature in keyboard music, string playing, and vocal ornamentation. Understanding alternés is crucial for historically informed performance practice, allowing musicians to accurately interpret and perform early music. The speed and duration of the alternation are key elements that contribute to the overall musical effect.
