A short, ephemeral salon piece by Otto Auerbach, reflecting the light classical style of the early 1900s. It features simple melodic lines supported by basic chordal accompaniment, characteristic of pedagogical material from this era.
Focus on balancing the melody clearly against the repetitive chordal accompaniment in the left hand.
Comparable difficulty and character — good candidates for what to learn next.
1904 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 1904 lasts about 3 minutes.
