Just for the record, Strauss did compose two full symphonies early in his career.I didn't want to put just operas because I love his other stuff and wanted it represented....and wish he had written full symphonies... so:
FAVORITES by the way....wouldn't know where to start rating 4 songs vs Frau Ohne Schatten:
Death and Transfiguration
Four Last Songs
Frau Ohne Schatten
Just today I heard a beautiful movement from the violin sonata in a student recital...gorgeous!
