Songwriting James Pankow has described the group's songwriting process as "organic", where one person comes up with a song and the other members come up with ideas for their parts. Pankow, one of the songwriters for the group, also has typically been arranger for the horn section. Robert Lamm, another of the group's songwriters, sees the group members' contributions to individual songs more as arranging than co-writing, and says his songs were "enhanced" in the process.
