"Largo" from the cello Sonata by Jean-Baptiste Loeillet (not to be confused with Jean-Baptiste Loeillet who is his cousin... confusing, isn't it?), transposed for trumpet.
Just for the record: I couldn't find the trumpet version, so I found the cello version and transposed it. The legato is probably fitting better the cello, not the trumpet. While playing it I played it differently than how is written. I also took the liberty to add some ornaments and take away others. Somehow felt better to me that way. I suggest you do the same, play it the way it fits you the best.
You may download the music sheet as PDF, or in MuseScore format, so you can edit, transpose, transcribe and customize it to your own needs.
