We discuss the counting of Nambu-Goldstone (NG) modes associated with thespontaneous breaking of higher-form global symmetries. Effective field theoriesof NG modes are developed based on symmetry breaking patterns, using ageneralized coset construction for higher-form symmetries. We derive a formulaof the number of gapless NG modes, which involves expectation values of thecommutators of conserved charges, possibly of different degrees.
