I've been doing some thinking about my preferences for rack toms. Of my original 10, 12, 14 tom configuration, I found that I phased out of using the 12 because I like the configuration of one up and one down AND I liked the voice of the 10 better for the note I wanted on the "up" tom.
I don't see many people playing a 10 up and 14 down. This has me wondering if the 10 that I have just has a lower tuning range than most 10s.
I have also tuned it into a range that I would use an 8, but I now have an 8 for that and they sound good together when I want those voices.
I believe the perceived note from the 10 is typically around F4/350Hz, but sometimes lower.
So the questions that arise for you all are:
If you have a tom tuned in this range, what size is it?
If you have a 10 inch tom, about what note or Hz is it tuned?
If you have a 12 inch tom, about what note or Hz is it tuned?
What neighboring tom intervals are involved for you?
If you need help answering the quantitative questions, I recommend an online piano and hitting the notes until you think you recognize the note of the tom in question.
