I spent most of last week at the Sixth Sakai Conference in Atlanta. I took along 3 CD’s containing a recording of Mozart’s Marriage of Figaro.  While in Atlanta I listened to most of CD 3, and came across one of my favorite sections, not too far into the CD.
On my return, I noted with pleasure the post Mozart’s entire musical works now free on Net, announcing that
Wolfgang Amadeus Mozart’s year-long 250th birthday party is ending on a high note with the musical scores of his complete works available from Monday for the first time free on the Internet.
The financial backing came from the Packard Humanities Institute of Los Altos, Calif. 
I decided to see if I could find the score for that section. I put on the CD, listened until I found that section, and learned it was “Ecco la marcia, the fourth th scene in Act 3. I went to the web site, and was then able to find the piece. It can be found at NMA II/5/16/1-2: The Marriage of Figaro Vols. 1-2, Edition (Finscher, 1973), page 432.
I also located another online version of the score at W. A. Mozart
Die Hochzeit des Figaro, Page 292, Courtesy of William and Gayle Cook Music Library, Indiana University School of Music. (I was pleasantly surprised to learn this came from the good folks at Indiana University. Indiana has a famous music school in addition to the Cook Music Library.)
I was able to locate the text of the section: Ecco la marcia:
N. 23. Finale
Ecco la marcia, andiamo;
ai vostri posti, oh belle,
ai vostri posti.
Susanna, dammi il braccio.
Here’s the march; let’s go
to your places, girls,
to your places.
Susanna, give me your arm.
I was also able to locate a performance via You Tube, Ecco la marcia, in a recent performance by the University of Texas Campus Opera Society. Listen for the march in the background right at the beginning. I think it’s supposed to be the band of a regiment.
My wife and I were in Salzburg in the summer of 2005. It’s a great place to vist — you hear Mozart’s music constantly. We visited two places where he lived. While in Vienna a few days earlier we stayed in a hotel in the building in which Mozart lived from 1780-1781, and also attended a concert in a room at the Hapsburg Palace in which he performed over two hundred years ago.
By the way, if you’re ever in NYC then I suggest a visit to the Morgan Library. They have an excellent collection of musical manuscripts, including works by Mozart and Beethoven written in their own hand.
Ecco la marcia, andiamo.
