I have a library of 250 horn charts from artists as diverse as Aretha Franklin, Bruno Mars, Reel Big Fish, Maceo Parker, The Mavericks and the McQuire Sisters. Any of the charts can be transposed to your key or adapted to your band's horn section.

I will send you my catalog upon request.
You won't get "generic" parts for Bb, Eb, and C instruments. Each chart is customized for your horn/ section.
If I don't have what you need, I can have it for you quickly.
I can also transcribe or copy your music, or create lead sheets in your key, in order to provide you with professional PDF files.
