The works of Weber comprehend examples of nearly all the vocal and instrumental forms, except the sacred oratorio. He completed and published six operas, and left fragments of three others. Of his first boyish effort, "Die Macht der Liebe und des Weins," not a bar has been discovered, and it is believed that he destroyed it. Of smaller dramatic works including the melodrama "Preciosa," the overture, and incidental music for "Turandot," airs for interpolation in operas of other composers, etc., he wrote twenty-eight. His cantatas, using the word in both its old and newer sense as a composition for soli and chorus with accompaniment, number eight. He wrote two masses and a separate offertory for each; ninety songs, ballads and romances for single voice with pianoforte or guitar accompaniment; nineteen part-songs for men's voices; fourteen canons, part-songs, etc., for mixed voices with and without accompaniment; and he arranged ten Scotch songs. The summary of his purely instrumental music is not so large. He was not a master of the great epic form, and the two symphonies which he composed have no significance in an estimate of his work. In addition to the overtures to his published operas he wrote three overtures which have appeared separately: that of "Peter Schmoll" published as "Grande Ouverture à plusieurs instruments," "Rübezahl," known as "Beherrscher der Geister," and "Jubel"; he also wrote five orchestral dances and marches. He composed three pianoforte concertos, ten smaller works with pianoforte accompaniment, thirteen concerted pieces for various solo instruments (clarinet, bassoon, flute and violoncello) and orchestra, four pianoforte sonatas, seventeen pianoforte pieces of various other forms for two hands (counting sets of Fughetti, Allemandes, Ecossaises and Waltzes as single numbers) and twenty similar pieces for four hands.
