If you're playing for a country crowd or a middle age and younger, the songs that are posted here are good. IMHO

If you are talking about 3/4 time in all it's beauty, you have to go back and dig. Out of a hundred waltzes you will find three or four that are very special. They bring a special feeling to 3/4 time, a feeling that reaches any age.
When I play a latin dance, I play a latin song, it was written for latin music, it let's you feel the latin.

Can you imagine playing one of the special waltzes on a job, it puts you in a special class of performers.

IMHO--Please.
