The first file is available in two different file formats, PDF or Sibelius. For PDF you need to have Adobe Acrobat on you computer. For Sibelius you will need the SCORCH plug-in, which is available on the Sibelius site. This allows you to both listen to and print the files. Also, the printing quality may be better than PDF.
I believe that church music does not have to be difficult to be effective. Many of my compositions are written for churches that have limited resources. Below are two free choir anthems based on hymn tunes by famous composers.
"How Wondrous and Great" SATB with piano or organ. Based on the hymn tyne LYONS attributed to Joseph Michael Haydn.
