text: The adjustment of intonation is most often accomplished with a short tuning slide between the neckpipe and the bell incorporating the bell bow (U-bend); this device was designed by the French maker François Riedlocker during the early 19th century and applied to French and British designs and later in the century to German and American models, though German trombones were built without tuning slides well into the 20th century.
