Thanks for the resource. I noticed on level 4, "amazing grace song", it is in 3/4 time and some of the measures have a half note with a triplet. If im not mistaken, I think that should be a dotted quarter note with a triplet so that it can equal three counts. I figured it was done this way for practical purposes. Regardless, this a very good resource. I definently need to work on my sight reading.
