Aristide Farrenc composed some pieces for the flute, but is best known as a writer on music. He took an important part in the 2nd edition of Fétis's 'Biographie universelle,' and wrote the biographical notices in Madame Farrenc's 'Trésor des Pianistes.' He also contributed critiques to 'La France musicale,' and 'La Revue de Musique ancienne et moderne' (Rennes 1858). Some of his valuable notes and unpublished articles are among the MSS. in the library of the Paris Conservatoire.
