Previous Next Contents Home Checking synchronous patterns In synchronous patterns, two throws are made on each beat. So if the right hand throws a 2, write 2 under the right hand throw two beats later. The right hand throw in the next bracket is two beats later. If the left hand throws a 4, write 4 under the left hand throw four beats later. The left hand throw two brackets later is four beats later. However if the left hand throws a crossing 4, it will be caught by the right hand, so write 4 under the right hand throw two brackets later. An example should help. Let’s check the pattern (6,4x)(6x,2)(4,2). First write 6 under the right hand throw six beats (ie three brackets) later:           (6,4x) (6x,2) (4,2)            6 Next write 4x under the right hand throw four beats (ie two brackets) later:           (6,4x) (6x,2) (4,2)            6            4x Now write 6x under the left hand throw six beats (ie three brackets) later:           (6,4x) (6x,2) (4,2)            6         6x 4x Now write 2 under the left hand throw two beats (ie one bracket) later:           (6,4x) (6x,2) (4,2)            6         6x 4x 2 Now write 4 under the right hand throw four beats (ie two brackets) later:           (6,4x) (6x,2) (4,2)            6      4  6x 4x 2 Finally write 2 under the left hand throw two beats (ie one brackt) later:           (6,4x) (6x,2) (4,2)            6 2    4  6x 4x 2 There is one number under each throw in the pattern, so (6,4x)(6x,2)(4,2) is a valid pattern.Reading the checking number in revers give this pattern:(6x,4)(2,6)(2,4x).
