fantastic visual/touch exploration of musicality and composition
This is fun for kids and adults. You can create a "score" simply by painting, which immediately gives sound. And you can play it back and scrub back and forth.
So kids can quickly sketch a "shape" and see what it sounds like, change instruments, then just clear it away and try something else.
you can play back either the way it's "written" or by the way you dragged your finger.
You can switch between instrument sets, so hear what your shape sounds like with different instruments.
Overall just a really direct fun experience of music and creation.
