Patrick: Schubert's works that conventionally get marshalled in the part-song category include at least one great masterpiece, where 'great' means large in size and forces as well as splendid in quality. I refer to the
Gesang der Geister uber den Wassern D714, a Goethe setting for 8 male voices, 2 violas, 2 cellos and double bass that for me is one of Schubert's very greatest works. It's a piece that needs something a bit bigger than a domestic acoustic IMHO. I have it on this CD
http://www.amazon.co.uk/Choruses-Aus...953359&sr=1-12 as well as in the big Sawallisch EMI box set on LP.
There are several other part-songs to die for (Der Gondelfahrer D804, Standchen D920, 23rd psalm D706, Nachthelle D892 come quickly to mind), but I don't often feel the need for many of the others.
