This page describes my approaches to the [[semiquartal]] (5L4s) mos or generator framework, firstly a contrapuntal approach and secondly based on a fictional tradition inspired by world musics such as maqam. | This page describes my approaches to the [[semiquartal]] (5L4s) mos or generator framework, firstly a contrapuntal approach and secondly based on a fictional tradition inspired by world musics such as maqam. | ||
