Implicating guitar to instrument.

A guitar is an instrument!

And a weapon. KABOOOOOONG!

if we are doing this we ought to go and implicate all the common instruments. Going in descending order we have

recorder 136
keyboard 134
flute 98

I don't know where the threshold for implications should be here, but at least the more common ones should be implicated. There's also a good chance I'm missing some, but that should be the bulk of the most important ones.

We've also got:
bow_(instrument) 19
drumsticks 12

Which are sort of ancillary, but may or may not be a good idea to implicate.

Holy crap there were a lot of alias/implication threads in the last 24 hours.

As for a threshold, I think 20 is usually a good number but I did these all because you went to the effort to look them up.

I changed triangle to triangle_(instrument) first, btw.

Edit: Oh, I didn't do bow_(instrument) or drumsticks yet. Waiting to see what others think. Though I imagine it won't hurt, and that the vast majority of the time they're depicted with an instrument anyway.
