Mostly I tune to the tone the shell produces when its thumped with no heads, rims, or tension rods.  Other easy-to-remember intervals I've used:

Minor thirds (Brahms Lullaby)
Taps
The first first 2, 3, or 4 notes of "In The Mood" (depending on how many toms)

It's nice when guitar players tell you what to do!  

I guess mine are tuned to 1-3-5.  I play the snare and ride tom together to make sure they resonate nicely together, then both toms, then snare and floor tom together.  Overall, to my ears anyway, they resonate and ring nicely.

Yes,  I Do mean Major 3rds.  The guitar player that I am working with plays Satriani Note for note.  I do like the horse race song tuning.
But it was his suggestion that convinced me to try it.  I just wondered how many different ways you could tune a drum set.  I am getting some good feedback.  Thanks,

Ranman,
Thanks for the link.  I do know how to tune my drums and I do have my personal favorite drum heads.  What I was looking for was more
the actual notes that people tune too.  I tuned to 1,3,5 for years and
I did like what it sounded like.  I really didn't know that a drumset could be tuned any other way.  About 5 or 6 years ago I met a very humble but killer guitar player that suggested that I tune like the race horse song.  I tried it and this tuning seemed to sound good on everything that I played.  I have been listening to some of these guys that tune to a note that is stamped inside the drum it self.  I guess DW does this.  I have been playing a set of Tama Star Classics for about 3 years and I love these drums better than any that I have played.  I am not sure if the shell note is what I am looking for.  Some drummers tune drums high and some tune in the middle and some tune low.  In my earlier days when I was really starting to playing drummers that I never thought I could play, I heard some earlier Journey before Steve Perry and the Drummer was Ansley Dunbar and he tuned really low.  I have looked for that sound.  My drum heads starting with my floor tom are fairly loose.  Just above any rattle.
I usually will start at the bass players low E I think and tune to the race horse song.  I do tune my snare kind of tight but I like my drums
to sound musical.  16in,14in,12in, two 10in's, 8in, 6in, and 14in. snare.
22in X 18in. Bass. The object of this message was to see how drummers tune differently like the one gentlemen said he tunes to the wedding song. That is cool and if it works for him then it is the right way for him.  I am going to probably stick to the Race Horse song.  It really works for me and I can thank, yes, a guitar player for suggesting it. I have not been doing this for so long or consider myself so good that I don't need to try anything new.  I may already seem a bit uncomfortable  to some guitar players because of the, I am the man pride, because since 1980 I not only play drums but I sing lead vocals too, I have even gone up front some but I do feel a bit naked without my drums. Thanks again,
                                        Nutty
                               
                   

While tweaking my 12" tom the other day, I thought of something - and I'm wondering if anyone here has tried it previously.  

It occurred to me...my toms (on the six-piece kit) tend to be tuned a third or fourth apart from one drum to the next.  Similarly, I realized that on each tom, I usually end up with the resonant head tuned higher than the resonant by - you guessed it - a third or a fourth.  

What I'm thinking now is, would it make sense to merge the two together?  In other words, start with my lowest-pitched tom, with the resonant tuned (for the sake of discussion) about a third higher than the batter.  Then, move on to the 14" tom, and tune its batter to the same pitch as the reso on the 15, and tune the 14" reso up a third (or fourth) higher...tune the next tom batter up to the same pitch as the 14" reso - and so on, and so on, and so on.  Whether the intervals are thirds, fourths, or something else, isn't the point - it's the matching of the pitch of one tom's resonant head with the pitch of the next tom's batter head.  

I haven't tried it yet, but for some reason, I find it an intriguing notion.  I may have some time later this week to try experimenting with this sort of tuning system, but I'm curious to know whether anyone here has tried it already.

Wow, This is good James and Rei, This kind of stuff is what I was looking for.  Some different Ideas.  I usually tune my bottom heads
the exact note of the race horse song because these heads change very little over time and then the top heads I try to keep the same.
I find it hard to stay in tune when one of my bottom heads go out.
You can try this next drum tuning.  Let us know how it turns out.

I think the wedding song is 1 3 5 Major 3rds.  Very interesting.
Seems we all tune to major or minor 3rds depending on taste.
I guess I have my answer then.  I would like to hear back about
James Walkers tuning Idea.
