BabyPianoToy2 is an Android app developed by DigitalToys.co.jp that aims to help children develop their musical potential in a fun and engaging way. This free app falls under the Games category and is specifically designed for children who are interested in music. One of the best features of this app is that it provides a unique approach not found in other piano apps.

The app features eight well-known nursery rhymes including Jingle Bell, Twinkle Twinkle Little Star, and Happy Birthday. It has three types of musical expressions for each song: melody, accompaniment, and performance. The app also offers four sound sources, including piano, electronic piano, pipe organ, and grand piano, and four drum sound sources to help children develop a sense of rhythm. Another great feature is that children can change the color of the piano toy body according to their individuality. Furthermore, the app provides a study of the sound system by displaying Doremi CDE and is available in both Japanese and English.
