El caballero de la rosa
Nast specialized in light and soubrette roles, especially Mozart, and she created the part of Sophie in "Der Rosenkavalier" in 1911. Her clear tone and lack of continuous vibrato were echoed by other sopranos of the period. She made some recordings which indicate high technical accomplishment, including her part in the trio from "Der Rosenkavalier". She also sang the part of Micaëla in the first recording of "Carmen". Nast died in Füssen.
