Triplets are one of those topics that look intimidating on paper but make complete sense the moment you hear them. In this video I explain ABRSM Grade 2 triplets from scratch — what they are, why they exist, and exactly how to notate them correctly for the exam.

The short version: in simple time, each beat normally divides into two. A triplet is what happens when you squeeze three notes into that same beat space instead. The feel changes — from duple to triple — but the beat itself stays the same length. Once that clicks, everything else follows.

Lesson Breakdown

  • The simple time rule: In a signature like 2/4, each crotchet beat naturally divides into two quavers [00:00:37].
  • The triplet exception: An ABRSM Grade 2 triplet squeezes three notes into the space normally occupied by two of the same value [00:01:54].
  • Notation: To mark this exception, a small ‘3’ is placed over the group of notes [00:03:00].
  • When to use a bracket: In 2/2 time, where beats are minims dividing into crotchets, the notes can’t be beamed together. In that case, a bracket is required to group the triplet — the ‘3’ alone isn’t enough [00:06:12].

Common Pitfalls in ABRSM Grade 2 Triplets

The most common mistake is miscounting the total beat value. The ‘3’ is a modifier — it changes how many notes fit into the beat, not the value of the notes themselves. So if you’re asked to complete a bar that includes a triplet, the surrounding notes still need to add up correctly to the time signature.

The other area where marks get lost is the 2/2 time signature. Because crotchets can’t be beamed like quavers, the bracket is mandatory. Without it, the examiner has no way of knowing where the triplet starts and ends. Don’t lose easy marks on something this simple.

What the Triplet Mark Tells You

When you see a triplet marking, it’s a signal that the beat has temporarily shifted from duple to triple division — three notes where two would normally go [00:04:11]. That’s all it is. Keep that in mind and the notation becomes straightforward.
