True. Jelly roll Morton is remembered as one of the earliest pianists to record jazz and the first celebrated composer in jazz
Jelly Roll Morton was America's first major jazz composer. Despite being a significant and acknowledged inventor throughout the changeover era from early to orchestral jazz, Morton had a penchant for inflating the truth about himself. As a result, his claim that he coined the name "jazz" is in doubt. Morton arrived in New York City with a diamond in his front tooth in 1911. He first performed "Jelly Roll Blues," which was published for orchestra in Chicago in 1915, making it possibly the first jazz orchestration ever produced. Several more Morton orchestrations would follow. Morton's most fruitful years were the 1920s.
