Pur ti miro is a duet taken from Monteverdi’s opera, L’incoronazione di Poppea, which premiered in 1643. In the opera this is a love duet sang between a soprano and a countertenor and is here transcribed as a trumpet and trombone duet. The original manuscript of the score does not actually exist and the only two surviving copies from the 1650s show significant differences from each other. There are even more uncertainties about the history of this piece as there is no record of the original cast, or how the opera was initially received by the public. The opera itself is generally accepted as part of the Monteverdi operatic canon, his last and perhaps his greatest work.
The accompaniment part can be played on both harpsichord and piano. This also works wonderfully for Cornett and Sackbut duet, a part in C is also provided for the first part.
