How Deep the Father's Love (Stuart Townend) custom arranged for string quartet with vocal solo with optional flute and lead sheet for optional rhythm. This would very well for a wedding, or other special service where only a string quartet and vocal would work. This can also be used as a worship setting for congregational singing. This is in the key of both D and E and should work with any vocal part for solo. You can add the optional flute and light rhythm should you so desire.
Be sure to upload the sample score and listen to the midi audio this arrangement. Note that there is no vocal part on the audio.
