To play more musically, you can imagine that the music you play is film music. Create a scene for every phrase you play and try to "accompany" this scene with your instrument. Make a whole story out of one piece and and use it to inspire your playing. Play the story rather than the notes. Of course, if it already is film music you are playing, you should have no problem finding the story!
