The above graphical output method is the result of our attempts to present an intuitive representation of our data.  The goal is to produce an output which is most useful for someone completely unfamiliar with graphical methods yet intimately familiar with music.  Thus, we graph each window as an image with colors assigned to the various values of the data inside the window.  The result is something that looks surprisingly like a musical score.  The more “intense” or colorful a particular region seems, the more likely it is to be a note played within that window.  The chromatic scale serves to display the merits of this startling technique with distinction.

The first graph below this paragraph is the graphical interpretation of Stravinsky’s Three Pieces for Clarinet using this method for processing our data described in this section.  It serves the same purpose as the preceding Stravinsky graphs.

The most useful application of this graphical method, however, is that one may readily view several notes playing at once.  This form is best embodied in the final two graphs.  To first gather some sense of how to interpret the graph when multiple instruments are playing, the second graph below this paragraph shows a stripped-down version of the output from our program when it is fed the first 90.703 seconds (4,000,000 samples) of Barber’s Adagio for Strings as played by a clarinet choir.  A choir in its most general sense is merely the gathering of multiple like-familied instruments.  That is, all sorts of vocal instrumentation (soprano, alto, tenor, bass) form the most standard interpretation of choir.  Thus, a clarinet choir is one in which several members of the clarinet family (Eb, Bb, A, Alto/Eb, Bass, Contrabass, etc.) play in one ensemble.  The final graph on this page displays the output for Barber’s Adagio For Strings in all its glory.
