"KOLORATUREN (COLORATURA) was commissioned by Froelich Film as a trailer to [its] feature Gitta Discovers Her Heart, starring a popular operetta singer ... Gitta Alpar. One hears Gitta singing, but sees only Fischinger's abstract designs ....

"The film was ordered as a rush job, and had to be delivered in three weeks. Fischinger locked himself in and worked steadily, completing it on time. Yet despite the rush, it shows no lack of care, no signs of haste. It is just as complicated and detailed as the other black and white studies, in fact containing the most sensational sequence in the whole series - the whirlpool and wipes that accompany the final high note." - Dr. William Moritz, Film Culture
