Hits such as "One O'clock Jump" and "Jumpin' at the Woodside" (from 1937 and 1938 respectively) helped to gain the band, now known as the Count Basie Orchestra, national and international fame. These tunes were what was known as 'head-arrangements'; not scored in individual parts but made up of riffs memorised by the band's members. Although some of the band's players, such as trombonist Eddie Durham, did contribute their own written arrangements at this time, it was these 'head-arrangements' that captured the imagination of the audience in New York and communicated the spirit of the band's members
