A jaunty Italian folk song. The cello part is written so that it can  also be played by a viola. If you have a guitarist or harpsichordist (or  another player of a chordal instrument) with you, you can expand (and  enrich) the piece to a trio. For this purpose, the chord symbols are  written down in the score and in the cello part.
An example of this can be seen and heard in this video:
