Free public domain sheet music from IMSLP / Petrucci Music Library
|Work Title||Sonata a quattro|

Of the 4 movements, the basso part is independent in the first, but more or less the same as the bass of the continuo part for the other three. An additional basso instrument is probably not necessary.
