Montessori materials are NOT toys, but educational materials. Proper use requires appropriate training.
Montessori materials may contain small, rough, sharp, or other elements that could cause injury or damage if used improperly.

 with adjustment zone
The long bars correspond to the bars in the rhythm boxes, but they are 4 bars.
Since a lot of 4-bar phrases can be found in music, these bars enable children to recreate, feel and make the beginning of a song or part of a piece audible. They can thus be picked out in isolation and practiced, researched and changed with ease.
