“Day Dreaming” is an English-language song composed by Jerome Kern, with lyrics by Gustav Kahn. It is written for voice and piano and is in B-flat major. The surviving published vocal score was issued in New York by T. B. Harms in 1941, as a six-page complete score. The work belongs to Kern’s early 20th-century output and is presented as a compact vocal song rather than an instrumental feature.
For performance, the principal musical focus is the relationship between the singer and piano accompaniment. The B-flat-major setting provides a clear tonal center for shaping the vocal line, while the keyboard part supplies the harmonic and rhythmic support. No separate instrumental parts, arrangements, or recorded performances are documented with the published score.
