Flute Solo???

So for the texas flute festival my flute teacher gave me a solo and told me to lok it up online to hear a recording, problem is she is out of town and i dunno what it is called. The sheet of music she gave me says B Major at the top and is by Karg-Elert. it also says In Tempo di Waltz. its in 3/4 time and the first measure has a triplet tied to an eighth note and then 4 more eighth notes. It is un accompanied. I have googled it and cannot find it anwhere!! please help?
