Traditional American music songs such as “When The Saints Go Marching In” are excellent pieces for developing an understanding of the style elements associated with the performance of 20th century popular music. There is opportunity for players to explore the arrangement - the bass line played by the pianist is open to being played with some rhythmic variation particularly during the playing of the repeat sections. Many melodies and lyrics that are recognised as spirituals are often a synthesis of several songs that had their origins as work songs before, during and after the American Civil War. Songs sung from the 1850’s and onwards were perhaps published around 1918 and then first recorded in the 1920’s. The history of the song is well documented and many there are performances to be discovered embracing a range of styles and different types of performing group. A soprano saxophone part appropriately transposed is appended to the full score.
