For the pitch,I'll slide the band (on the reed) to the portion of the reed that most closely resembles what I would classify as a younger buck grunt,ie,higher pitch-if you slide the band farther than necessary ,it will actually sound more like a doe bleat. For the cadence,I'll usually do a tending grunt-short quick grunts,making sure to change the direction I'm facing each time. Deeper buck grunts sound cool and like a big nasty swamp donkey,but I don't always think a buck wants to face the biggest,baddest buck on the planet. Maybe they like going into fights they think they can win?
