Allegretto in G Major, No.8, Op.50 by Mauro Giuliani (1781-1829) – Lesson, Performance, and Sheet Music. 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 5 level depending on your tempo and the muting of the bass notes. Here’s the YouTube Link for this lesson if you want to watch it there.
