As a composer, his salon compositions are noteworthy, especially the Air de Ballet and Romance; a gavotte, and the vocal Lieblingswalzer.

[2] His three brothers, Sally, Emil, and Max Liebling, were also successful pianists, and all four of them studied the piano with Franz Liszt at some point during their training.

[3] In 1885 he was the accompanist of the violinist sisters Teresa and Maria Milanollo for their tour of Germany, including performances at the Berliner Philharmonie.

[7] From December 1897 through July 1898 Liebling gave a series of ten recitals at St James's Hall in London which were well received by critics; drawing particular praise for his performances of works by Beethoven, Liszt, and Chopin in addition to his own compositions.

[12] He performed with that organization again in the world premiere of Macpherson's Concertstück, a work for piano and orchestra, at St James's Hall on 11 May 1898.

[17] He taught at the Hollywood Conservatory of Music in California in the early 1930s,[19] where one of his students was composer and pianist Edith Wire.
