Instead of taking your whole choir to a workshop or clinic, invite an experienced director to come work with your group in your own rehearsal space. 

Workshops can be custom designed to focus on the questions or problems you and your group may have.

Some topics to consider:

• Switching bells 
• Legato playing
• Percussive techniques (Mallet, Martellato, Ring-touch, etc.)
• Correct Ringing Style

 These and many other topics can be covered in a one or two hour session custom designed for your group.
