Only if you fallaciously reason that positive command to do A, means negative command to do B in support of A.

The best way I've heard this argued is by the example of Go'd's commandment in building the arc.

He said to make it of gopher wood which would exclude say pine or any other wood for that matter.

To make melody in your heart excludes making melody with say a organ or any other instrument for that matter.

Do you see my reasoning?

Is it flawed?
