If you don't listen to anything else in this thread, please listen to this. Solo violin, accompanied by English horn and orchestra to John Williams' score to the film
Schindler's List. The English horn is such a plaintive, emotional instrument and the player is profoundly affected by the music -- but stays the consummate professional and plays her heart out.
If you don't have a tear coursing down your cheek at the end of this short clip, you are not alive.
P.S. -- the camera work is so good you can see the rosin coming off the violinist's bow.
P.P.S. -- Much information about the English horn (cor anglais) player at the YT page.
