This is the first movement of Telemann's Sonata in E-flat major, TWV 41:EsA1, a charming Baroque piece often found in collections for wind instruments. It features typical Baroque ornamentation and a graceful melodic line.
Focus on clean articulation and graceful embellishments.
Bassoon Sonata, TWV 41:EsA1 is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7.
You should be comfortable at Henle level 5 — meaning you can already play level 4–5 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
