A variant study in B-flat minor, this work emphasizes the kinetic energy of ascending intervals within a four-part contrapuntal framework. It is technically demanding due to the requirement of maintaining independent phrasing across complex textures.
Concentrate on precise finger-independence to ensure the canonic subjects maintain their character throughout.
Comparable difficulty and character — good candidates for what to learn next.
Canon 4-voice ascending 6th b moll is rated Henle level 5 of 9 — late intermediate repertoire, roughly ABRSM grades 6–7. In the RCM system it corresponds to about level 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.
A typical performance of Canon 4-voice ascending 6th b moll lasts about 3 minutes.
