A delicate miniature by the Belgian composer Jef Tinel. The work is characterized by its transparent texture and gentle melodic contour, typical of late 19th-century Flemish salon piano music.
The main difficulty lies in balancing the voices to ensure the melody remains prominent throughout the thicker chordal passages.
Comparable difficulty and character — good candidates for what to learn next.
't Is schoon is rated Henle level 3 of 9 — late beginner repertoire, roughly ABRSM grades 4–5. In the RCM system it corresponds to about level 4.
You should be comfortable at Henle level 3 — meaning you can already play level 2–3 pieces cleanly. Learning it one level early is possible as a stretch piece, but more than that usually leads to months of frustration.
A typical performance of 't Is schoon lasts about 2 minutes.
