Well being a drummer myself, I'm just in awe of much flak goes toward a drummer in this thread. Insulted really. Drummers are pretty independent with what they do. For us, there really isn't a wrong way to do something.
There are 3 major methods of tuning drums.
1) Tune the top head (batter) lower than the bottom head (resonant). This is the more popular tuning among drummers in rock and punk and hip hop etc.
This achieves the punchy sound.
2) Tune the top head equal to the bottom head This usually achieves a more open sound.
3)Tune top head higher than bottom head. This is more popular among jazz drummers. Again, this method achieves a more open, resonant sound, more particular in bass drums and toms.
Just like the others said, tuning drums is fairly difficult, so to go and call a drummer a "dumbass" for tuning drums the way he/she wants it is just being ignorant. First off all, You got two different tones to deal with. 1, the top head, and 2, the bottom head. The top head head alone produces a note of its own, and the bottom head likewise. And blending the two together only adds in to the difficulty of the drums.
In the world of "tuning" for drummers, we all tune in intervals, most usually. When Depicting the distance in tone of the top head and the bottom head, most drummers like to tune it in a 3rd interval. While some like 5ths, and some even 4ths.
This also goes for depicting the distance between different sized toms. In a situation where there are only 3 toms, the rack toms, or first two smallest are distanced in notes by a 3rd interval, then, from the 2nd to the 3rd tom, the largest, it would usually be distanced by a 5th interval.
in situations where there are 4 or more toms, all the toms would be distanced by 3rd intervals. You see, toms are like chords, believe it or not for those of you thinking that we drummers are just dumbshits and don't know anything about notes. In chords, if you have 2 notes, then you have a wide range of intervals to deal with. But as you add more notes, the intervals became smaller and smaller, similar to how if you add more marbles to a jar the space empty volume becomes less and less.
Also, in addition to the "drummers don't know anything with tuning by ear", drummers do, in fact, tune their toms to songs or familiar scales alike. Some drummers tune their toms to the "Wedding March", "Mary had a Little Lamb", or some other little tune such as that.
As for snare drums and kick drums, obviously it'll be hard to get a note out of a snare, and obviously NEVER should obtain a note out of a kick drum, call it dumbshit or not, its a no no, and if you have any objections, try recording a kick drum tuned to something like F then mix that in with the different tones of the guitars, vocals, bass guitar, keyboard, toms, snare, effects. Won't get it to stand out much right? Yeah, don't need much to think about that.
SO generally drummers would tune snares and kicks bassed on the effect they desire, If you want a tight resonant sound, you use the 1st method for drum tuning. If you want a resonant sound, either 2 or 3, a phat sound, or thick, then maybe 3.
So calling drummers stupid, idiotic, don't know how to tune is only showing your own amount of knowledge about it. IT IS in fact, hard to tune drums properly, if it ever existed. Drummers tune the way THEY want it. I would think that it be up to them on how they want to record it in the first place. I mean, that is what they're paying to record for right? To record them, NOT give them a tutorial on how to tune drums?
I can understand that some younger drummers or less experienced don't know the lines of how to get a "relative tone" out of their toms or whatever, but that's a skill that is mastered as they mature. It isn't something learned right on the spot. I mean, you wouldn't learn how to operate a rocket in 30 min would you?
