A Dictionary of Music and Musicians/Bravura
BRAVURA (Ital., courage, bravery). A style of both music and execution involving the display of unusual brilliancy and technical power; music written to task the ability and test the courage of the artist. Thus 'Let the bright Seraphim' (Samson), 'Gli angui d'inferno' (Flauto magico), and 'Non piu mesta' (Cenerentola) are bravura songs, requiring a compass and a power of execution out of the common.
The notion of effect for effect's sake is perhaps involved in the term. Beethoven therefore can never be said to have written bravura pieces, though many of his pieces require the greatest skill and are extremely brilliant.
'Con bravura' and 'Allegro di bravura' are similarly used to denote fire and brilliancy.[ G. ]
