Oryginally I wrote this piece for my band that includes electric guitar, electric bass, piano and synth (wich are played by the same person) and drums. This was just a "musical background" for a song, but few days ago I began to give to the midi files classical sounds just to hear how it sounds like.
So the guitar turn into an Harp, the Bass into Cello, the right hand of the pianist an English Horn, the left into Bass. In the Chorus pianist play with the right hand the synth, and it became a couple of violins. I only introduce two trumpets at the beginning.
I hope I've respect the right extension of each instruments, and I hope the parts are really playable.
Unfortunately I'didn't record this piece with my band yet. I'm gonna do it!
Thank you everybody for encouraging me!
