I just used this didge for a presentation at the school where my wife teaches- Go Mustangs! The tuning is perfectly on D with the first trumpet also in D. Everything about this didge is totally smooth and controllable. And by smooth, I mean butter. It was very easy to take confidence in front of an audience of over 600 people with this didge as my facilitator. I basically just breathed and listened and it did the rest. It was nice to have a chorus of 200 children singing along for a few of the pieces, and just to see 200 children being awesome. This instrument has a lot of volume and a beautiful sensitivity of volume range, being capable of playing extremely softly and as loud and hard as you freakin' can. The first few trumpets are so easy and dependably right there every time I reach for them. The overblown can be pushed to a dramatic cracking shatter. All this while riding on air shocks, and maybe you get little wings.
