Self control

The thought just occurred to me, I admit, for the very first time, after a brief conversation with my dear wife.  The church Fathers direct us to keep the Jesus prayer on our lips and on our mind, at all times.  Obviously, this is not taken crassly literally, but the idea is not to allow whatsoever thought to come to mind or to allow whatsoever comment to pass from our lips.
This is about self control.
The thought that came to me was this.  I saw a connection between self control, emotions and music.  Since we are called to manifest self control, as a fruit of the spirit, this would mean that we are not to haphazardly allow emotions to run amok.  I had the thought, right or wrong, of using music, and its powerful ability to communicate emotion, to direct our emotions. It seems to me that far too often our emotional state runs loose and free with us as a slave to the whole thing.
What about using music as a tool, just like any other tool, to get us to a right place?  Could we learn from this practice?
