A battery-free musical board book! This wonderful book (ages 0+) will introduce your child to 7 musical instruments. Seven charming illustrations will immerse you and your little one in the magical world of classical music. All you need to do to fully immerse yourself is tap your phone against the cover or scan the QR code. The book introduces you to the sounds of the instruments: bassoon, piano, violin, harp, tuba, organ, and marimba. There's no need to buy, change, or throw away batteries; the musical sequences are long, and the music is played in high-quality, not distorted, performance. This book truly introduces children to the sounds of musical instruments, as all seven parts were recorded specifically for the book by talented Russian solo musicians. The piano piece, for example, was written and performed by a 10-year-old blind musician, and believe me, it's amazing! All illustrations are done by the artist in calm pastel shades - specifically so as not to irritate the already overloaded psyche of modern children.
