Mr. Martins had already programmed nearly all of next season before he stepped down, and it will look familiar to City Ballet fans: 30 works by George Balanchine, the company’s co-founder and guiding artistic spirit; 11 by Jerome Robbins; a pair of full-length ballets by Mr. Martins, “La Sylphide” and “The Sleeping Beauty”; and a host of more recent works, including ballets by Alexei Ratmansky and Christopher Wheeldon.

Mr. Martins had commissioned four new works: one by Matthew Neenan, the choreographer in residence at Pennsylvania Ballet and the co-founder of BalletX in Philadelphia; one by Gianna Reisen, a young dancer and choreographer who won praise for her first work for the company in September; and two by Mr. Peck. One of Mr. Peck’s new works will be set to a newly commissioned score by Sufjan Stevens, his frequent collaborator, with orchestrations by the composer Timo Andres.

The new team commissioned two more. To choose them, Mr. Stafford said he turned for advice to Mr. Peck, who follows new developments in dance closely. They settled on two choreographers who have yet to create dances for major ballet companies.

To make a work for the fall gala, the company picked Mr. Abraham — the founder of the modern dance company Abraham.In.Motion, now called A.I.M., and a MacArthur fellowship winner — who has made dances for Alvin Ailey American Dance Theater and the dancer Wendy Whelan. And the company asked Ms. Portner, whose work includes viral social media posts, a Justin Bieber video seen more than 50 million times and the West End production of “Bat Out of Hell — The Musical,” to create a new work for the company to dance in January.
