[chorizo]

Thanks Dewy. I will have a listen to that and try it out over the weekend.

The reason i got onto the subject in the first place was from hearing a band practicing and thinking the drums sound particularly awful. Not only did they sound like they were not "tuned" to work together (almost as if the "intervals" in changing between the types of drum were all wrong), they also sounded out of tune with music the rest of the band was playing and I was wondering why because they are percussive after all, and wondered why other drum sounded so right or "in tune".

For me the effect was more noticable with the toms and Bass although to snare can definitely sound "off" too. I then just assumed that drums were tuned somehow (as you can tell i know nothing about drum kit).

I will try to find an example of where toms seem to me to be "in tune" with the song. Perhaps you cannot necessarily find the key from their sound alone but maybe some idea of the notes contained in the key whether it be the root, fifth or whatever as Steve suggested (if i'm understanding correctly).
