What is ? Tongue Drum Tank Drum Tongue Pan - which and what to buy.

I am "horrible" at making reviews. But have been getting a lot of questions lately, regarding what and which to buy. So I thought I ll make a video - uncut, unedited, no effects video - to describe the difference (& sound quality) between these drums, The 1st picture : mic placement was to show the distance btwn the drum(s) and the mics/recorder(Tascam DR40) for this video.
Sonic quality or sound projection- to me- is important to the player.(extremely important to me)
Personal use/meditation etc- maybe not so.
I find the bigger drums has better projection(loudness) and personally perfect for my practice, which is vibration healing.
You can always amplify these drums by miking them/connecting to amplifier, if needed- but that's a difference topic.
This video includes some of the drums I own.
Let me know if you have any questions.
Have a blessed day!
