I'm going to infer that this is NOT the HBDs first year in the district and that he has more than a few years experience on you.
That being said - don't worry about this, it's totally normal. He has had more time to build a report with the kids than you, and more time to find himself as a teacher. I've known some very good teachers with great bands who run rehearsals that are far more chaotic than I can handle (I'm more like what you describe yourself to be).
As a young teacher, you need establish courtesy, routine, and expectations LONG before you worry about "like". Some kids will never "like" you, but if you are fair and consistent, they will respect you and be able function in class.
No teacher is going to have everyone like them. If there are multiple directors, some will get along better with one director than the other(s). It's just human nature. You don't always have to like someone to work with them.
From my first gig as the only BD at a podunk school: Some kid scrawled "Mr. Shaftoe SUCKS" on the BH door. My principal's response? "First - if you're not making SOMEBODY mad, you're probably not doing your job. Second, they called you MISTER. There's some degree of respect there!"
I'm in an interesting situation. This is my first year in this particular district, a small 3A. There are two band directors: myself, and the head director. After teaching in two other districts, I am completely happy here. HD and I get along incredibly well, we have support from admin, a great budget, and I could keep going on about the wonderful things this district has to offer.
There is one thing that I am struggling with here, and I am hoping that maybe I could get some advice or encouragement. My HD is not a disciplinarian. He jokes and laughs with the kids, and lets them get away with more sloppy rehearsal etiquette than I do. I am much more firm and structured than he is, and that's just our different personalities, I think.
Here lately, I've been noticing that as a whole, the band kids in this district gravitate toward him. How could they not? It is starting to wear on me, though. The kids in my junior high band are always asking about him if he isn't there. One beginner flat out told me during class that she likes him more than me. I was just passing out new music when I noticed a sticky note on a door written by a kid that says "Mr. X is the best."
Maybe I'm being petty, maybe I need to take a mental health day, but I'm really struggling with this. I talk to the kids every free chance that I get, and I am trying to build relationships with them. My band rehearses well and I have no doubt that they'll do well at UIL, but being a band director is more than just UIL ratings. Any advice?
