1. This is one of the melodies you have already worked with. Use Orff instruments (glockenspiel or a xylophone) to play it. Rehearse enough till you can play it properly. See that there is a banjo sound in the score, click on the instrument name to know something about it.

2. Let's check by watching the video if you sound like it.

3. We are going to keep on practising variations. First, remember what a rhythmic motif  was and so, instead of the pairs of quavers in the score, play the first note as a crotchet and omit the second quaver (don't change the quavers in anacrusis). Look at this score to better understand it. Try it and rehearse. You will have to sound the same as the following video. If you can do it properly, congratulations! You can perform variations.
