As far as I can tell, a lot of the tuning process is based on personal preference. The only thing that you need to remember is that the smaller ones should sound higher and the bigger ones should sound lower.For tuning toms, do you only have to tune the batter head? I didnt see him tune the bottom side of the tom.
Also, is there a website where i can hear the basic pitch that each drum should sound like?
I know some of it is preference, but for a beginner, it might be helpful for me.
