The song was composed by Mykola Leontovych and it’s a very popular Christmas song.
The boomwhackers arrangement I suggest can be played by 5 or more students,
In the following lessons you will find a close score of the song arranged for boomwhackers and two suggested lesson plans. One is for five students and the second one is for 8 students.
Of course these are only my suggestions.
There are other ways of playing Carol of the Bells with the boomwhackers. You may play only the melody or you may play only the accompaniment. It depends on the age and musical skills of your students and of course on how many students you have.
