Does it replace other instruction books or standard notation?

It is not intended to.  It would be foolish to ignore the wisdom found in the fine standard instruction books that percussion teachers have learned to rely upon for many years, and the many new books, some of which will become regarded as classic in years to come.  And of course any serious musician wants to be able to read standard notation as it is such an important means of communicating musical ideas among musicians.  Responsible teachers will always provide heavy emphasis on reading exercises in standard notation and it is asserted that ChoomBoonk makes the study of standard notation easier by its taking over of coordination problems which normally burden reading exercises.  It is recommended that respected "classic" instruction books in standard notation be assigned right alongside ChoomBoonk and eventually 4-limb coordination books written in standard notation.
