Giovanni Gabrieli’s Canzon Septimi Toni a 8 is a landmark work of late Renaissance Venetian polychoral style, notable for its antiphonal dialogue between two choirs of instruments and clear sectional contrasts. It was published in 1597 in Sacrae Symphoniae, a collection of sacred and instrumental works. While often performed by horns of various types, the instrumentation was unspecified and most any collection of instruments with appropriate ranges will work well.

The source used for this arrangement is in volume 10 of the Opera Omnia (collected works) of Giovanni Gabrieli, edited by Richard Charteris.
