A simple and common way to create such an oscillations is to take for example a simple chord harping-waving that contains also with the previous rules less than 50% of the time also notes outside the chord , and then half of this simple theme translate it one octave higher, and so oscillate between the two octaves. Normally the initial non-translated melody would have intervals of 2nd, 3rd, and 5th. The interval of 3rd will become 6th , the interval of 5th, a 4th and an interval of 2nd , will become 7nth. In this way also the sttaitical profile of such melodies will have more frequently high intervals of 5th, 6th, 7nth and 8th compared to intervals of 2nds (see post 93 ) .g. the folk Irish melody Kerry Polka below
We remind the reader that this should be read in the context of general method of creating melodies like in posts 92 and 103
