Ratings and Reviews

Great App!


My 15 month old son loves this app! He's very much an on-the-go kind of baby but this app can give me a few minutes to relax when I need it. The songs are all nursery rhymes that I can sing along with to him. And I've been impressed how much he's learning to interact with the game. I highly recommend this app! Its free with no ads too!

Musical osmosis


This is a great app for tiny little kids, who really just want to play. If you're looking for something to teach your kids to read music, this probably isn't it. But this does some good stuff through musical games using good graphics and high-quality music. My one complaint is the stupid bongo accompaniment on the rhythm-birds screen -- it can't be turned off, and it's in 4 with one, unchanging tempo. At level three, it becomes a more complicated pattern than the quarter, quarter, eighth-eighth, quarter (doom, gak, doom-doom, gak), but you are still expected to play every song to the same ridiculous bongo. (Thing repetitive beat poetry style bongo with She'll be Comin' 'Round the Mountain…) Worst of all, level one includes Happy Birthday -- the meter doesn't even match the accompaniment!



This app offers a lot. The page with the most depth is the notes page. Here you get to see songs written out on a musical staff, drag the notes around to change the songs, read the letter names for each of the notes, and learn how eighth, quarter, and half notes differ. You can also play back the music with different instruments, including solfege (sung do-re-mi). It's really an innovative way to expose music notation to young children.
