Instrumental Music Needed for Recorded Song.

My dad wrote a few songs that I have recordings of. But they are all cappella and he has now passed. I would love to put some instrumental music to them for a completed song. A simple piano maybe a few other instruments. I have cleaned up the file and have attached it. All his songs are written similar to Christian hymns and I would want to keep the music in melody to what he sings. I have a few others that I would like to do if this one turns out really well.
