Description

  The present invention relates to a music teaching book with a sound generator suitable for music education and play for infants and children.

  Music education in early childhood and childhood is very meaningful, and from this perspective, there have been known books that integrate a musical score and a sound generator such as an electronic musical instrument as in prior arts 1 and 2. .

In the above prior art, a musical score unit in which a large number of musical scores are combined is pasted and integrated on the upper half of a back cover made of cardboard, and an electronic musical instrument such as a piano is fixed on the lower half. When used, the book is opened, the page of the musical score part is opened, and the electronic musical instrument is operated while viewing the page.
However, in the prior art, the musical score is placed in the same plane as the electronic musical instrument during performance, so the performer has to look at the musical score from above while operating the electronic musical instrument. Also, because it was close to an unreasonable posture, there was a problem that the neck and the like were easy to get tired and it was difficult to learn for a long time.

As a countermeasure, the musical score part is separable from the cover and is mounted on a separately prepared musical score stand. However, in this method, not only the goodness of the book in which the musical instrument and the score are combined together is lost, but it is troublesome to restore the separated score, so that the score part is easily lost. .
