First, how do you define “hogaku”? Is it “traditional Japanese music,” or just “music played with traditional Japanese instruments”
Good point! I realize that hougaku/hogaku is the wrong word. 和楽器 Waggaki/Wagaki is the more appropriate word, as that describes Japanese instruments, whereas hogaku is more for the traditional styles of music. Of course, I do like the way ‘hogaku’ rolls off the tongue more than ‘wagaki’, but whaddayagonnado?
To clarify, Bachido will stay! There is no way I’m changing a title as badass as that. 
Also, though the symbol is three bachi, which indicates shamisen, the feeling of that symbol will evolve from just shamisen to the “bachido way.” Though the name/image if the Bachido title/mon are outwardly shamisen being, it’ll be just as TJ said, " Bachido is a symbol of how this community began. It is a core meaning to what we started with and it defines us." It has become a symbol of community in this musical world more than just of a three stringed instrument. Something I never dreamed would happen.
So, reminding why this is all happening anyway:
Some members have an interest in shakuhachi, which I think would be great if Papa Abbott could make a crash course to help them.
Also, Masahiro wants to include taiko drums.
I can’t bring myself to say, “there’s no place for shakuhachi/taiko/etc in Bachido because it’s not shamisen” because holding back such education is not the Bachido way. 
On the other hand, If the site remains as it is, a potentially awesome shakuhachi crash course and taiko drum stuff will be hidden away in some page. Just like in the Toneway store (which focuses on American mountain music), Shamisen of Japan and Blowing Zen are placed at the end under the title “And now, for something completely different…”
Basically, if I am gonna put time/energy/money into developing a shakuhachi crash course (which I want to do), I don’t want it be under a title which says, “And now, for something completely different…” or “You may find this interesting”.
Rather, I’d like Bachido to be set up so these other great Japanese instruments and their enthusiasts can find a home here.
Also, I assure you that with my brother Luke’s talent in design/placement, these other instruments included won’t interfere/dilute the experience you have here. In fact, you will probably find it more enriching! 
Finally! This will not be happening over night. Rather, just changing the subtitle will set the foundation to allow for what can build up over the coming years.
