This piece by Blas María de Colomer is a pedagogical character piece common in 19th-century Spanish conservatories. It uses simple diatonic progressions to teach basic coordination.
At Henle 2 this is a beginner-level piece, where steady coordination between the hands is the main hurdle. The main demands: precise articulation — the difference between crisp and blurred is the piece; fine finger independence within the hand; and Alberti-bass accompaniment kept quiet and even under the melody.
Students should ensure the Alberti bass accompaniment remains lighter than the melodic line.
Comparable difficulty and character — good candidates for what to learn next.
A level or two down with the same spirit — ideal if this piece is still out of reach.

Do, ré, me, fa, sol is rated Henle level 2 of 9 — beginner repertoire, roughly ABRSM grades 2–3. In the RCM system it corresponds to about level 2.
You should be comfortable at Henle level 2 — meaning you can already play level 1–2 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 Do, ré, me, fa, sol lasts about 2 minutes.
