Historically informed performance (HIP) is a musical discipline aimed at recreating music that’s true to its period, as it would have been produced and performed in salons and theatres some two or three hundred years ago.
While we may never know exactly how a Bach violin sonata or a Mozart symphony sounded when first written and performed, music scholars can show how the instruments were made and played in each period, allowing us to experience a little vicarious musical time travel in the auditorium and in recordings.
