Two moderate-tempo Viennese Waltzes I like: Breathe (2am) - Anna Nalick This Year's Love - David Grey
My favorite waltzes Sleepsong - Secret Garden and Deja De LLorar - Found on Ballroom Passion, however you can find a faster version on itunes
Lots of things with that name on iTunes that aren't waltzes. Try the version by Manuel Franjo on the album Solo Por Tu Amor.
Just a side note here.... I have been obsessed with the Wildhorn musical "Scarlet Pimpernel"... while downloading the music.. in error .. I downloaded a song..called "Scarlet Pimpernel".... it is a Waltz.... and just used it to satisfy a bridezilla... last Friday...as a "in the pinch" fill in for her band which had to cancel..... the small waltz ... "Scarlet Pimpernel" is by BLACK SABBATH.... lolololol.... and no.. I did not tell her or her guest.. who made the recording.... what bridezilla doesn't know.. wont hurt her.. Oberon
For practice, I am fond of "Where Is Your Heart?" by the Percy Faith Orchestra. It's from a movie that my grandmother likes, Moulin Rouge (no, not the Nicole Kidman movie that came later, during the 2000's)...
