"Historically, the trill has acquired associations with doom, gloom, and even the occult. More specifically, two noteworthy composers, Guiseppe Tartini and Franz Schubert, adopted the trill to express a sense of melancholy in some of the most definitive pieces of their oeuvre. While these composers were certainly not the only ones to use the trill in incisive ways, their use of the classic embellishment distinguished their work."
