I've charted horn section arrangements for well over 100 contemporary worship songs, from Hillsongs to Chris Tomlin, to Israel Houghton, for my own church. Most arrangements are for songs that don't have horns in the original recording.
My charts have been written to accommodate reasonably skilled amateur players (the talent available to me in my own church). In the charts I've written, trombone and trumpet usually double each other on the most critical line, and tenor sax fills out a little harmony. This can be really handy if you have a weak trumpet player or a weak bone player. If one of the two can cover the line strong, you're set. The parts go to three-part harmony when covering block chords, for example, in choruses.
I have spent hundreds of hours making these arrangements. Since I don't have the rights to the songs, I'm making them available to others as free aids to worship music performance- on the condition that the arrangements I share will be used in places of worship where the venue has obtained the proper licensing (such as CCLI) for the live reproduction of the music.
To obtain these charts, left-click my saxguy007 forum name (not my avatar pic) and left-click on either Personal Message or Email, and use that feature to send me your email address. DO NOT REPLY IN THIS THREAD TO GET MY CHARTS! It's not wise to put your email address out there in a forum post, and I don't visit this forum often.
Once I have your email address, I will email a link to you to download a large (100MB) zip file of all my charts from a Google documents account. It takes too much time to pick and choose charts, so I just send everyone a link to get the whole shebang.
Once you download and unzip the file (using any common zip utility), you would just have to get free Finale reader from www.finalemusic.com to open and print them, and even transpose them. Some of my older charts are in ScoreWriter, where I "printed" that chart as a pdf (no transposition possible).
The form of a song might differ between how this church or that one covers the song, but at least you'd get the riffs for the choruses. I would only ask in return that if you successfully use one or more of my charts, perhaps with some adaptation, that you take the time to let me know, so that I might continue bothering to do this.
