When going back into the first part for the second time around rather than playing a long A on the A string I use a C natural B A G sharp A . This acts as a nice link between the second and first parts and it allows the melody flow better.

As bars 1,3,5,7 of the second part begin with the same phrase I use a simple variation at the first bar of the second part. This variation wil fit in any of the aforesaid bars. .Rather than playing FGAF GFADÆ I play GF ADÆFA GFADÆ
