Would you have any suggestion of an acceptable standard piece of the kind of this one???
I assume they want you to improvise on those themes. Dave showed all the possibilities of Take 5 leaving very little room for you to come up with a new angle. The two pieces they suggest leave a lot more room for you. There are a ton of jazz pieces which are standards because we can go all sorts of places from their basic themes. Don't choose a theme that will constrain you.
