This work is from Giuliani's Studio per la Chitarra, Op.1, Part 2. These studies lean more toward a technique exercise experience but there are a number of nice musical moments making them enjoyable while offering numerous benefits for musical and technical development as well as reading skills and interval recognition of the guitar.
I have used Giuliani’s fingerings for the majority of this edition (around 95%). However, his smaller guitar, use of the left hand thumb, and some irregularities have led to small changes and modernization of fingerings for this edition. Giuliani’s fingerings are not ideal in terms of legato phrasing and smooth technical movements. His fingerings emphasize position playing and the physical workout involved in jumping from shape to shape in close proximity. There are benefits to learning to “cover up” or “hide” non-legato fingerings by making our movements as quick and sustained as possible. Here's the YouTube Lesson Link if you want to watch it there.
