Here are four more combined-patterns pairs.

(If you haven't already, work through Page One of this set first.)

Here are two pairings from the remaining unused exercises, selected purely on the basis of their musicality.

Take creative control, and task yourself with deciding upon another, say, four pairings. Use any exercises, previously used or not.

'Switching off' and 'just' practicing exercises is not the best use of your time. You should always be alert, listening hard to your playing and exercising your musical judgement.
