We are told specifically to sing and make melody in our hearts. There is no mention of mechanical instruments of music in this command. Also, there are no examples of the 1st century church using them in their worship. That is the Scriptural evidence that we have. If you want, you can even look at historical evidence. It wasn't until several centuries after the church began that mechanical instruments of music were used in Christian worship.
I'm not violating the command you cite ... by incorporating musical instruments to accompany singing in worship.
The command says to make melody in my heart ... which I do ... in worship and in my general christian life ... and my ability to make music in my heart is not hampered by the accompaniment of instrumental music.
