A pleasing simple music creation app by the band, Lullatone. This app features a grid of 30 grey raindrop images. When you tap a raindrop, it makes a sound and turns a color (that drop only ever makes that particular sound and turns that particular color). Over the next six seconds, the color fades, but the color and sound will repeat every six seconds until you reset the grid or tap that particular drop again. This allows for some interesting music looping activities for older kids through adults, or just playful exploration (are all of the drops in this row the same color? Same sound? What happens if I try this pattern?). All of the notes sound harmonious with all of the other notes and (other then the second column which is a longer sustained flute note) all of the sounds are short, like the plinking of raindrops, so you can't really make terrible music no matter what you try. And that's the beauty of this app. It's so simple to use that you can totally use this app to entertain a baby on an airplane without annoying the people sitting next to you (well, maybe if you have the volume turned WAY up, but you wouldn't do that, would you? This one is fun just with the colors and no sound if you really need it to be silent!) or you can use it to relax yourself if you're feeling fidgety. There's also a metronome option should you desire a beat. If your older child is using the app and has already explored the basics, try asking them challenge questions like, "how many notes can you time to sound in unison?" or "can you play a recgonizable tune?" Uncluttered and modern design and free to download make this app just a perfect little treat. Enjoy!
