In most cases, I find it beneficial to fully notate ‘open charts’ for students. Don’t worry; this isn’t cheating – it’s called making a learning aid!  You may think this defeats the object, but think about it for a second. Through a comparison between the ‘open’ and (for use of a better word) ‘closed’ versions of the chart,  students can begin to develop an understanding of what is required of them. Similarly, it can provide them with material to practise which will allow them greater freedom to improvise in the long run. This is especially useful in the interpretation of the slashed notation sections.
