 In Buah Rindu , particularly its earlier poems , Amir shows an affinity for using traditional Malay poetic forms such as the quatrain ( found in pantun and syair ) . However , unlike the highly fixed traditional forms , Amir mixes the rhyming patterns ; for instance , one quatrain may have a monorhyme ( seloka ) while the next may have an alternating simple 4 @-@ line ( pantun ) pattern . Lines are generally divided by a clear caesura , and in some cases even two . The caesura may not always be in the centre of a line ; it is at times towards the front , and at times towards the rear .
