According to the performance note, Alexander's Ragtime Band, was composed in 1911 by Irving Berlin and this famous piece in popular ragtime is one of Berlin's earliest and most enduring hits. The bugle call quaver passages make an effective contrast with the ragtime style whn played without rythmic deviation.
As I generally play bass or tenor, it is a special joy doing the bugle call bits.
