Canon Triplex is a contemporary contrapuntal study by Rob Peters. It explores strict imitative techniques within a modern harmonic framework.
Maintaining rhythmic precision across the three independent voices is the primary challenge.
Comparable difficulty and character — good candidates for what to learn next.
Canon Triplex (Op.14) is rated Henle level 4 of 9 — intermediate repertoire, roughly ABRSM grades 5–6. In the RCM system it corresponds to about level 6.
You should be comfortable at Henle level 4 — meaning you can already play level 3–4 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 Triplex (Op.14) lasts about 3 minutes.
Canon Triplex (Op.14) is available as free public-domain sheet music on IMSLP — the score is linked directly from this page.
