A Tokyo-based publisher of music books has debuted texts that let children combine piano study with English in an effort to help them continue playing instruments.

Zen-On Music Co.'s three-book series "Piano Discoveries,' which came out Friday, was originally published by Lorenz Corp. in Ohio.

The Japanese version contains songs, musical terms and simple English phrases to instruct how to play piano tunes, accompanied by Japanese translations of the songs and detailed instructions.
