The original 19th century German trombones were constructed with much larger bores and flared bells. This was in response to the growth of orchestra sizes during the transition from the late classical to the mid Romantic period. They provided a darker, richer sound ideal for Bruckner, Brahms, Mahler & Wagner. These instruments from c.1860 are in pitched Eb, Bb and Bb & F.
