Ernst Krenek is noted and often criticized for the diversity of his overall output. However, one finds that his entire output is held together by a unique temperament regardless of stylistic changes. It is significant to compare the piano works to one another as the piano was the instrument he repeatedly turned to while testing new stylistic ideas. In writing about Krenek's music, Glenn Gould states eloquently and concisely that three qualities prevail in all of Krenek's mature output: the lyric, elegiac, and euphonic. These qualities are present in the early Toccata und Chaconne uber den Chorale, "Ja, ich glaub an Jesum Christum," Op. 13. It is lyrical in that melody is of utmost importance. One finds that melodic writing prevails in the other piano works as well regardless of when they were written. The elegiac also permeates the work. The Toccata and Chaconne shares with other later works this quality of seriousness, repose, and deep meaning. The Toccata and Chaconne is also euphonic. Krenek's overall style is one which does not shock or offend an audience. In a detailed comparison of the Toccata and Chaconne to later piano works, one may clearly see what Krenek specifically does musically to create this sense of the lyric, elegiac and euphonic in his overall output.
