Found an old device I did over a year ago, it's based on something Alan Silvestri did in the "Night At The Museum" score.
Since I did this a while back, the score has a few misplaced dynamic markings and also lacks slur markings for the fills for some reason. I left the mistakes in there just so you can see what not to do:) NotePerformer wasn't available when I composed this so the mp3 is a "real" mock-up instead of the usual NP-output.
As for the actual device it's a call-and-answer between woods/strings (call) and solo clarinet/bassoon/tuba (answer). The solo instruments has freer phrasing and contrasts the rather static rhythms of the combined sections. All this takes place over a pedal (viola tremolo) and ostinato (harp). Again, the harp could be argued to be a pedal as well since it stays on the same note throughout.
The idea behind the device is simple, but that's also what makes it so malleable and useful in the long run. You could come up with countless variations on this simple concept alone, and that's ideally what a good device is, something that can be used in many different contexts.
As you can see in the Elements score the melody is both green and red. I use this when there's two melodies that are of equal importance that overlaps, much clearer than just using one color.
The pedal is made up of celli/violas/bassoon and harp. Besides the Celli that's doubled by the bassoon they all have their own figures, but since it's all centered around the same note the combined effect is a pedal.
I analyzed the bass drum hit as a fill since it really sticks out at the end. When it comes to percussion, I usually try to see which Element it fits together with the best and label it accordingly.
I've noticed that on some of the Elements Pdf's the highlights are a bit out of place when opening it in the OS X preview. Try using adobe reader instead if you have that problem
This is a device I picked up from James Newton Howards score to "Nanny McPhee and the Big Bang". Always loved this type of writing so it was fun to try to get the feel right.
As you can see in the score it only consists of 3 elements. The melody and the fills trade off in a call and answer fashion. First time around the violins answer doubled with a marimba at the end of the phrase. The second fill with the celeste and glock is an arpeggiated Cmin/maj7 chord and finally the harp ends with a descending gliss using the C melodic minor scale. Once again the ostinato is there to keep it moving forward without bringing too much attention to itself, and in this case it also acts as a pedal note since it's stays on the tonic C throughout.
