You can substitute Tek for Ka, and vice versa, if it works for you. Change what you play to fit or complement the situation. Please keep in mind that these notations are just suggestions . The same goes for other rhythms with an even number of counts. Easy rhythms are quick to learn, memorable and short.
Tough rhythms take a while to learn or re-learn.
An SCA drummer known as Angus gave me permission to post his message here from the SCA-Drummers list . A riq is an Egyptian tambourine, usually with an inlaid wood frame around 8 to 9 inches in diameter, with 5 sets of brass jingles in two rows around the frame. The head is traditionally fish, although you can find them with goat or with synthetic heads. The jingles are one of the most important things to look for in a good riq since much of the playing on the riq is done on the jingles themselves. They need to be thick enough to give a good sound, the slots cut in the frame where they sit can't be too tight, or too loose or they will not swing properly.
