Through-Composed
A structure that moves forward with its text instead of repeating whole stanzas

Through-composed music moves forward with its text or drama instead of repeating a whole melody for each stanza. It is common in art song, opera scenes and musical theatre: when the emotion changes, so does the music, and motives return only when memory needs stirring. Schubert's "Erlkönig" is the famous example, with distinct music for narrator, father, son and Erlking.
Through-composed is the opposite of strophic, but not a ban on repetition. Motives, harmonic patterns or accompanimental figures may return; what does not return is a whole stanza-shaped melody. Judge it by whether sections recur per stanza, not by whether anything repeats.
The risk is that constant change leaves the ear without a foothold. Composers hold such pieces together with tonal return, a recurring motive or a refrain-like phrase, so constant motion still feels like one work.
