His popular work The Storks (1902) with Guy F. Steeley led to his work with Baum, as he was recommended by M. Witmark & Sons, the publisher. He also wrote songs with lyricist Arthur Gillespie, two of which appeared, credited to Baum, in The Woggle-Bug. His other stage works include Pussy in a Corner (1904), The Forbidden Land (1904), The American Girl (1906), and The Maid and the Millionaire (1907).
Chapin took up writing, having written the book and lyrics for The Maid and the Millionaire, and then produced a 1908 fantasy novel modeled on the Oz books titled Toodles of Treasure Town and her Snow Manitoba, which he followed with Pinkey and the Plumed Knight (1909), both illustrated by Merle De Vore Johnson.
On November 11, 1912, he opened a four-act farce called Cause Of Death on Broadway at the Gaiety Theatre, which was fairly successful, in spite of many negative reviews such that one reviewer felt the need to quote reviews from The Sun and others, while The New York Times found the play funny and well acted. Tefft Johnson directed a film version of Cause Of Death in 1914 with Harry Davenport, Hughie Mack, and Charles Brown in the title roles (men with the initials, COD).
From 1914–1932, Chapin worked as a scenarist in Hollywood. Chapin returned to composing with Unashamed, a 1938 nudist romance.
