So I finally found a way to finish my piece. People in the class (and Dr. Ross) suggested that I end with something really climactic, a "big bang". This is pretty easy to do on drums and even on piano, but I needed to find a way to bring this to the violin. What I ended up doing was bringing back the tritone idea heard earlier in the violin part. I started it off in the piano and then the violin came in with it. To really build up to the last little bit I had the piano and violin rise chromatically, fisrt in eighth notes and then in sixteenth notes. I really think this brought the tension up to the climax well. Finally, the violin part sustains a b (the key which most of the piece is in) and the drums and piano cue each other into the last two beats.
