Radamés Gnattali was a Brazilian composer, pianist and conductor born in Porto Alegre in 1906 who began his professional career in the 1920s, working in radio, theatre and orchestral settings and composing across classical and popular genres. His output bridged classical forms and Brazilian popular styles—including choro, samba and salon music—through chamber works, concertos, film and radio arrangements and orchestral pieces that combine formal composition with popular idioms.
