Historical performance practices refer to the methods and techniques used by musicians and performers to recreate works from the past, particularly from the Baroque, Classical, and Romantic periods. These practices emphasize authenticity, aiming to reflect the original intentions of composers like Bach and Beethoven by using period instruments and performance styles. These practices often involve research into historical documents, such as manuscripts and treatises, to understand how music was performed in its time. Musicians may study aspects like ornamentation, tempo, and dynamics to achieve a sound that is true to the era, enhancing the listener's experience of historical works.
