||"Four By Four" was written by Dean Sorenson in 2013. This chart was commissioned by the Bucknell University Jazz Ensemble. It is a straight-ahead swinger that uses 4th and 4s all over the place. There are 4ths in the melody and in many of the harmonies. There is a quartet within the big band at letter N. The solo section (beginning at letter I) has changes in Tenor 1, Trpt. 2, and Trom. 2. The changes are modal and very approachable so the solo section can easily be opened up. Top Trpt. note = B above the staff.
