Musical instruments can enhance the singing of praise to the Lord. Musical instruments were obviously considered a help to praise in the Old Testament. It seems strange to say that something God thought was a blessing in the Old Testament is now forbidden in the New Testament church.
Since instrumental music has the Old Testament precedent of being approved of God ("musical instruments of God"
1 Chronicles 16:42), and there is no evidence that there was a time when this approval ceased, we have biblical authority for its validity.
We are authorized to use “psalms” in the NT (
Ephesians 5:19;
Colossians 3:16).
Ephesians 5:19 says "..speaking to one another with psalms, hymns and spiritual songs.." and correspondingly
Colossians 3:16 says to, "..admonish one another with psalms, hymns and spiritual songs." The word "psalm" in the Greek dictionary, definition (#5568): "A set piece of music, i.e. a sacred ode (accompanied with the voice, harp, or other instrument)." The root word of psalm means "to twitch, twang or pluck," such as pluck a string of a musical instrument."

The words "making melody" are used in
Ephesians 5:19, but "how" this is done is found in
Isaiah 23:16, and it is with a musical instrument:" Take an harp, go about the city, thou harlot that hast been forgotten; make sweet melody, sing many songs, that thou mayest be remembered."
Also,
Amos 5:23 speaks of "the melody of thy viols," which is also reference to a musical instrument. So if "the Bible interprets itself," these passages show "how" to make melody – with musical instruments.
If certain churches want to leave out musical instruments in their worship, then that is their prerogative but nowhere does does the Bible forbid musical instruments like David used and as the apostle Paul instructed.
