This article lists the various treatments given by Franz Liszt to the works of almost 100 other composers.
These treatments included transcriptions for other instruments (predominantly solo piano), arrangements, orchestrations, fantaisies, reminiscences, paraphrases, illustrations, variations, and editions.
In most cases, Liszt arranged only one or two pieces by a composer, but he delved more deeply into the works of Bach, Beethoven, Berlioz, Donizetti, Mendelssohn, Meyerbeer, Mozart, Rossini, Schubert, Verdi, and Wagner.
The earliest-born composer whose works Liszt dealt with was Orlande de Lassus (born c. 1532).
Note: The Mazurka pour piano composée par un amateur de St. Pétersbourg, paraphrasée par F. L. (S.384) was based on a mazurka that has often been misattributed to Alyabyev, but was in fact written by Mikhail Vielgorsky.
