Edited sentence: According to Gillespie's autobiography, this was originally the result of accidental damage caused during a job on January 6, 1953, but the constriction caused by the bending altered the tone of the instrument, and Gillespie liked the effect.According to this account (from British journalist Pat Brand) Gillespie was able to try out the horn and the experience led him, much later, to commission a similar horn for himself.Gillespie came across an English trumpeter who was using such an instrument because his vision was poor and the horn made reading music easier.Gillespie's biographer Alyn Shipton writes that Gillespie likely got the idea when he saw a similar instrument in 1937 in Manchester, England while on tour with the Teddy Hill Orchestra.Whatever the origins of Gillespie's upswept trumpet, by June, 1954, Gillespie was using a professionally manufactured horn of this design, and it was to become a visual trademark for him for the rest of his life
