Don Juan and Eine Alpensinfonie are orchestral tone poems by Richard Strauss, composed in 1888 and 1915 respectively. Don Juan showcases Strauss's early breakthrough in large-scale tone-poem writing with vivid orchestration and motivic transformation, while Eine Alpensinfonie is a later, expansive programme symphony that depicts an alpine ascent through richly coloured orchestration and advanced chromatic harmony, reflecting his move towards more pictorial, orchestral narrative forms.
