Ständchen, D.920, op. posth.135, "Zögernd, leise"

"Ständchen", D 920/921 (also known as "Notturno") is a part song for alto solo, chorus, and piano by Franz Schubert. He composed it in Vienna in July 1827, setting words by Franz Grillparzer ("Zögernd leise, in des Dunkels nächt'ger Hülle").

Schubert wrote two versions, for male and female chorus, originally catalogued as:
D 920, for alto solo, TTBB chorus & piano
D 921, for alto solo, SSAA chorus & piano, Op. 135(p)

The latest update of Deutsch's catalogue places both versions under D 920, and D 921 is no longer used.
