6/8 Time Signature Metronome — Compound Duple

Free metronome in 6/8 — compound duple meter. Six eighth-note beats grouped in two sets of three. The meter of jigs, barcarolles, and lilting folk music.

6/8 — How it feels

6/8 is a compound meter: six eighth notes that are grouped 3+3, producing two main beats each with a built-in triplet feel. This gives 6/8 its characteristic lilt — a gentle rocking or swaying motion that is distinct from both the marching duple of 2/4 and the spinning triple of 3/4. At faster tempos, 6/8 is felt as TWO beats (not six), each subdivided into three, which is why it underlies the Irish jig, the barcarolle, and the 'slow 12/8' feel of many soul and R&B ballads.

Music in 6/8

  • The Irish jig — arguably the most recognized 6/8 groove in the world, with its bouncy, forward-tumbling momentum
  • Chopin's and Mendelssohn's barcarolles, where 6/8 imitates the rocking of a gondola on water
  • Many classic pop and R&B ballads that are 'felt in six': slower 6/8 can produce a rich, rolling groove that sits between a waltz and a slow march

Practice tips for 6/8

  1. At slow practice tempos, count all six eighth notes ('1-2-3-4-5-6'); at performance tempo, shift to counting only the two main beats ('1-...-2-...') so you feel the compound grouping rather than six individual pulses.
  2. The most common 6/8 mistake is playing it like alternating triplets in 3/4 — the accent must land on beats 1 AND 4 (the start of each group of three), not just on beat 1. Practice with a heavy clap on both 1 and 4 until the two-beat frame is locked in.
