Ask her how long she has been doing practicing.
If she is doing ballet she maybe into jazz they seem to go one on one. Ask her about music .. but get into the dept of the music she likes. This will be along the lines of classical or jazz .. maybe even opra. If you dont know anything about the tunes that she listens to. ..
remember then go pick up a cd. And listen to them. But dont tell her you are doing this !!! ..
when you are talking on the phone or on a date just have them playing in the car or the back ground. Dont bring it up to her attention. Let her ask .. hey isnt that .." insert name here"..
and being a smooth DJ .. say .. well you mentioned it the other day and i thoguht i would just check it out and I really like it .. and name something you really like about the song. Tell her how it makes you feel !!
Or something that you learned about the composer.
