Momo plays Jean-Philippe Rameau's "Musette en Rondeau" accompanied by her teacher Carl. Rameau (1683 – 1764) was one of the most important French composers of the 18th century.
This arrangement is by Richard Wright and published in One + One Volume 2 (Chanterelle). It appears on the ABRSM Grade 3 guitar syllabus (List A).
Well played, Momo!
