Christian music is music created by or adapted for the Christian church. It also includes Contemporary Christian music, in which the music explores Christian themes but is designed to be played in places other than churches. Music during service for many churches is a big part of the worship. Hymns are sung, psalms are vocalized and spiritual songs are uplifted to praise God. Sometimes, musical instruments are played while singing is implemented in the service. On the other hand, some times churches use just a cappella to worship God. At times, just musical instruments are only used to express praise towards God. All of these ways are used by one church or another in this period of time.

There is record of the earliest music of the Christian church in a few New Testament books of what are probably hymns. Some of these fragments are still sung as hymns today in the Orthodox Church, including "Awake, awake O sleeper" on the occasion of someone's baptism.

Being Jewish, Jesus and his disciples would most likely have sung the psalms from memory. However, without a centralised music industry, the repertoire of ordinary people was much greater than it is today, so they probably knew other songs too. Early Christians continued to sing the psalms much as they were sung in the synagogues in the first century.
