This book will soon be available for Apple and Android Readers, Tablets and Phones.
Practicing the exercises in The Jazz Drumming Workbook will introduce the aspiring Jazz Drummer to the rhythms and co-ordination needed to play Jazz drums and keep time in a Jazz band. You must listen to Jazz recordings, go to Jazz Clubs and Concerts, watch famous Jazz Musicians on YouTube and play Jazz music to learn how to apply the rhythms and co-ordination gained from practicing these exercises to a musical performance. These exercises cannot make you a Jazz drummer, only experience playing Jazz with other musicians can do that for you.
When practicing the Jazz Cymbal Time Comping Exercises it is important to recognize that the cymbal is the lead voice in Jazz Drumming and the drums should not be played so loud as to obscure the Jazz Cymbal Rhythm, unless there is a musical reason to do so, when playing with others.
While these exercises could be memorized and repeated in a performance, that should not be your goal. It is better to get familiar with these rhythms and this kind of co-ordination and then play Jazz and improvise your comping by responding to what you hear the band playing, rather than imposing an exercise on the music. Remember this is Jazz and the goal is to improvise and express yourself, not execute an exercise while you play with others.
This book does not cover the topics of playing time with Brushes, "Trading Fours or Eights" or Drum Soloing. I did not include Brushes because there are already a number of very good texts and videos on this subject. As for "Trading Fours or Eights" and Drum Soloing, these two related topics could fill another book. They would need a discussion of playing techniques, musical form, motifs, theme and variation and other subjects from the world of music theory.
While these subjects are related to Jazz drumming they are not necessary for your job of keeping time for the band, which is your primary responsibility, and the reason you are there playing with other musicians. Learn to play solid time first! If you don't keep good time with others it will really show when you solo. No one will know what you are saying musically if they can't feel your expression of the time. Drum soloing is an abstract art. There is no melody or harmony for the listener to follow. Only your placement of rhythms on your drums and cymbals in the flow of time is going on. If that flow is disturbed or not happening the audience and your band mates will quickly lose interest in what you are playing. Time, Time, Time. You must play in time and know where you are in the music. When you learn those skills then you will be able to play the song all alone, Solo!
