"Christian piano art music" is a small genre, each piece of which belongs seemingly to either Christian music or art music, but by definition to both of them. In spite of its merits this genre has been ignored both by the concert hall because of its religiosity and by the church because of its artistry. However, since God is the One who has infinite creativity and is pleased with our various musical praises, both congregational praise and artistic musical praise has to be dedicated to Him. In chapters 2-5, after the history of music--Christian music, art music, and Christian art music--is examined from a biblical perspective of human history (Creation-the Fall-Redemption-Consummation), the significance of Christian art music is discussed, especially in light of God's common grace and special grace. After discussing the merits of instrumental praise, in chapters 6-9, the selected repertoire of Christian piano art music is introduced, being categorized into four groups--works using hymn or chorale tunes, works related to the Bible, works expressing Christian faith symbolically, and abstract piano works dedicated to God. Finally, the calling as "Christian culture makers" is discussed.
