The Incredibly Useful Ensemble Series is an expandable and flexible format allowing performance by as few as four and as many as four thousand players. The first and second parts are doublesat the octave to enable the settings to be utilized as full band or orchestra pieces. Each set offers two works, usually contrasting in style but complimentary in playing difficulty. Transposed parts in B-flat, E-flat, and F are included along with concert pitch and bass clef.
