First, things were very simple - mandatory participation in the drum circles by each family member (except Xander), simple rythm (ok, total absence of).
Then things got a bit more complicated with multiple drums and complex composition.
Finally, Mark achieved mastery of drumming and became a marching band of one! He marches around the house and says "marching-drumming, marching-drumming" (in Russian he says ходить-банить). He also found a book with a picture of an animal marching band - elephants and rhynos drumming and marching around the house (thank you, Sandra Boyton!). So Mark gets that book out every morning, find a picture of the marching band, studies it for a few seconds, and then starts his marching-drumming practice.
Барабаны- для крутых пацанов!
