Two of Verdi's most well-known operas, La traviata and Rigoletto, unusually, both end very decisively in D♭ minor. For clarity and simplicity, however, D♭ minor is usually notated as its enharmonic equivalent of C♯ minor, as it is, for example, in the second and third measures of Amy Beach's Canticle of the Sun. Mahler's thematic motif "der kleine Appell" ("call to order") from his Fourth and Fifth Symphonies is similarly notated. In his Symphony No. 4 (first movement) it is in D♭ minor, but in his Symphony No. 5 it is in C♯ minor. In the Adagio of his Symphony No. 9 a solo bassoon interpolation following the main theme appears first in D♭ minor, returning twice more notated in C♯ minor. Likewise, in the Adagio of Bruckner's Symphony No. 8, phrases that are tonally in D♭ minor are notated as C♯ minor.
