"La muette" was innovative in a number of ways. First, it marked the introduction into opera of mime and gesture as an integral part of an opera plot (although these formats were familiar to Parisian audiences from ballet and mélodrame). Also, its historic setting, liberal political implications, use of popular melodies, handling of large orchestra and chorus and spectacular stage effects immediately marked it as different from preceding types of opera, in retrospect earning it the title of the first of the genre of grand opera. The journal "Pandore" commented after the premiere "for a long time, enlightened critics have thought that alongside the old "tragédie lyrique" it was possible to have a more realistic and natural drama which might suit the dignity of this theatre." The new genre was consolidated by Rossini's "Guillaume Tell" (1829) and Meyerbeer's "Robert le diable" (1831).
