The first is 'Aire de Hueya' by Adrien Politi from 'Play Guitar in Concert'. I came across this book in a beautiful music shop in Bruges, like stepping back in time, but with a great range of scores. Like all Michael Langer edited books, arrangements are neat, easy to read with helpful fingering.
The others are from the fantastic book 'Modern Times' which features pieces from grade 2 to 6, great tunes, but even the easy ones have rewarding challenges. Most demanding is playing legato and keeping the melody singing out.
