In general, there are no teaches on the tapes. Students are expected to study the list of calls or concepts for the week and come prepared to execute them. The lists are available on the web; see below.
There is presently no definitive reference available for C4. The dancers who are participating in the creation of this series used Galburt's Glossary Bill Heimann's Concept Survival Guide, and Ben Rubright's Pocket Reference of C4 Calls and Concepts. Neither the Glossary nor the Pocket Reference utilize complete definitions; both are intended as quick references rather than total documentation.
For this reason, and because C4 is an incredibly complex activity, you may have questions. I will be happy to answer any questions which come up while doing any of these dances. You can email me at firstname.lastname@example.org and I will answer to the best of my ability.
The series was not completed; there are some concepts which should have been done on one last recording. However, there is sufficient information to enable a talented dancer to become proficient at C4.
The order of presentation is a loose approximation of frequency of use, with the most common C4 calls being presented first. This is of course a subjective ordering; every caller prefers certain calls over others. I have reviewed and attempted to incorporate the lists of some of the major C4 callers into this ordering.
