First, tuning escapes a lot of drummers because of problems with the drum itself. Dings in the edges, out of round, bent hoops, damaged collars in the heads, etc....does not take much of any of this to add complexity to the process. Assuming all is good with the drum, I can offer some pointers.
#1 - The notion that a drum has one pitch that will make it come alive is difficult to swallow. I agree they all have ranges, but that is a factor of the composition of the drum, harwdare, and head. If there was only one magic spot in a wood instrument, you would never be able to tune a guitar. Each type of drum will have a range where it breathes and will choke above that or loose it's tone below that.
#2 - I was fortunate to have spent a lot of time early on with some really good drum tuners. The primary skill to learn in tuning (IMHO) is recognizing that point when the head is just getting it's lowest tone at each lug. It it actually something you FEEL when you tap it with the tip of your finger more than it is listening to a sound. The head just starts getting enough tension to hold firm when you tap it and a clear tone is present versus a thump. Using a star type pattern you can quickly set the drum to this feel...and the drum will be amazingly even when you tap it with a stick. It will also be at it's lowest fundamental in it's range. It's pretty simple to raise the pitch from there and keep it all even.
#3 - New Heads - Another anomaly in tuning is the adjustments that happen to the head as it seats itself and loosens in the collar. All heads take time to really seat on the drum and stay where you tune them. Remo takes a little more time than others, but they sound great. The way you can tell if a head has become seated is to find that lowest fundamental tension and then press down on the head with the heel of your hand. If the tension is lowered below the fundamental, the head is still adjusting in it's collar.
What I find is that drummers have varying strategies for tuning and never really get enough experience with one to learn the nuances with it. I am not a fan of the tension tuners as they ignore problems with the drum or head as I listed above. Many drums have things you have to adjust for when tuning...the head may all read the same tension, but it will not be in tune.
Tuning to a note is OK if you know one you prefer in the tuning range of the drum...you still have to know how to get the drum head in tune first before giong to the note you want.
