This is a great site for downloading sheet music, and the majority of our contemporary music was sourced from here. They have a huge catalogue (over 300,000 arrangements) and provide tools to let you transpose the score, which can be really useful if they original key doesn't suit a singer's preferred range.

The official web site for Keith and Kristyn Getty, the writers of many wonderful contemporary worship songs that we play regularly at Holy Trinity. They provide some very inspirational material on their site, and regularly give away free downloads of sheet music.

For the Trinity Singers we obtain much of our sheet music from ChoralWiki, which is home to the Choral Public Domain Library of over 32,000 choral and vocal works from over 3000 composers — much of which is available for free download and use.
