Performance and Lesson for Grazioso, No.2, Op.50 by Mauro Giuliani (1781-1829). This is from my PDF or hardcopy sheet music edition for classical guitar: Le Papillon, No. 1-32, Op.50 by Mauro Giuliani. Grades 1-7 and includes both a notation-only edition and a tab edition.
Le Papillon (The Butterfly), Op. 50 by Mauro Giuliani consists of 32 pieces published by Giuliani in Vienna in 1815. The works are presented progressively from easy to mid-intermediate depending on the tempo. Le Papillon is a beautiful set of works which are perfect for students, professionals playing gigs, or players looking for nice easy pieces to practice or perform.
I would place this study at approximately the grade 2 level depending on your tempo. Here’s the YouTube Link for this lesson if you want to watch it there.
