Strangely enough, I have no clue how to incorporate this in ritual. It's an odd idea that I just thought of.
Not sure where to start.
Then its best not to. Rituals are rarely made better by whimsically adding "cool stuff" to them. If you have a particular spell that would necessitate or in some way benefit from a enchanted instrument then analyze exactly makes it necessary, and use magick to enhance that aspect. Otherwise, you just wast time and energy trying to shoehorn in something that does not really fit.
You asked about how wise it would be to enchant the instrument but did not say why you thought it would help or even in what way it could. Before you start on the particulars of enchanting have a purpose in mind. Often once you look at the intended purpose you find magick is not needed. For example, you use the ukulele to bring you happiness. Fair enough, do you need a spell to do that? You already have that.
