There is no command for it's use in the church, there is no example of it being used by the church, there is no hint that it was used. If we truly love the Lord the positive command to sing would be sufficient to exclude instrumental music from the worship. An aid is something that does not change the basic command enables one to expedited the command. A songbook does not change the basic command. Even when the songbook is used it doesn't change the command.
Instrumental music is different because it changes the basic of singing.
If the Lord had commanded us to make music the instrument of music would have been an aid. The Bible doesn't say not to use it. The Bible doesn't have to specify everything that might ever be declared by God to be wrong. We have already discussed the principle that when God is specific in a certain area he excludes all other options. Those under the Old Law used instrumental music with the approval of God.
