Cornet or Trumpet Solo.

Por una cabeza, literally translated as "by a head (of a horse)" in Spanish (meaning a horse winning a race by one head's distance), is one of the most famous and popular Argentine tangos.
Composer Carlos Gardel (11 December 1890 – 24 June 1935) was a singer, songwriter and actor, and is perhaps the most prominent figure in the history of tango. The music has appeared in numerous TV and Film soundtracks, perhaps most memorably in the famous dancing scene featuring Al Pacino in Scent of a Woman.
This extended arrangement for cornet (or trumpet) incorporates a cadenza and newly written interludes.
