Here is my bell table for the children to select bells.  The bells at the back are the chromatic and extra range bells.  I got the bells from MES (music education supplies).  They are great and they are cheap but do not last forever.  It’s best to buy 3 or 4 of the octave bells and one set of the chromatic range for a whole class.  That will cost you about $100 in total.  Then you will need to replace one octave every 2 or 3 years as they get worn out pretty quickly.  This is an inexpensive way of performing music.  In a later post I will explain how we perform them in class.
