Repertoire
There always have to be some Latin tunes, maybe by A. C. Jobim, or even something more Cuban, like "Oye Como Va". I played violin in a salsa band for a few year. The violin is more common in Cuba that you might expect.
Also, I like to add a few jazz originals that have become standards, like "A Night in Tunisia", "Recordame" or "Spain".
Then there are the tunes that not many other people play, "Joy" by Gerry Niewood, or Ralph Towner's "Icarus". Jarrett's "Memories of Tomorrow" and "Country". Kenny Wheeler's "Everbody's Song but my Own".
The list is always changing. Sometimes I am asked to
play to a theme, such as tunes from particular countries to accompany
regional dishes for a restaurant's themed night. You can see a fuller list here
