Guilherme Daddi was a key figure in Portugal’s musical life in the nineteenth-century. Amongst his compositions are a series of powerfully virtuosic piano pieces, largely based on popular operatic themes or else sequences of waltzes and other dances. From a later generation was José Viana da Mota, one of the great virtuosi of the time whose fusion of classical-romantic traditions with nationalist elements was inspired by Portuguese songs and dances.
