first we tried the 19" and the pitch was way to high. then we tried the 16" but it arrived damaged. so we splurged and got the 22". wow. not only is it the coolest sound you'll ever hear the pitch is so deep that you can feel it in your chest. my 2 year old boy makes "parade" every 10 min. he's super stoked. and as a purcussionist myself, i'm very happy we went with something deep instead of something high pitched like a snare drum. our friend has a baby snare kit for his son, but the poor kid doesn't ever get to play cause he's always being told to be quiet. haha. buy this drum.
