Subdivision Metronome

Practise eighth notes, sixteenth notes, triplets, sixteenth-note triplets, and sextuplets with counting cues and visual beat feedback.

Set an exact tempo, read the bar, and hear where each division lands inside the beat — then measure your own placement with the tap pad.

What this tool includes

Read the bar

One column per position, grouped by beat, with the count written under each position and the grouping printed where a division splits inside the beat.

Say the division

Numbers, Kodály, Takadimi and Eastman syllables, with the beat number in the first slot of every beat.

Choose the accents

Beat one leads by default, or make every beat the same. Silencing the beat tier leaves you carrying the pulse on your own.

Measure your placement

Tap along to see the last deviation in milliseconds, the mean signed and absolute error, and the position you rush most.

How to use this tool

  1. Start at 60 BPM and speak the count before playing.
  2. Keep the quarter-note pulse in your foot while clapping the smaller divisions.
  3. Set the beat tier to Silent and carry the pulse yourself for one bar.
  4. Switch subdivision without changing tempo, then increase speed only when every note remains even.
  5. Tap every position for two bars and fix the worst position before raising the tempo.

Practice tips

  • Beat one leads by default on this page: the first beat of the bar is accented and the later beats land on the normal tier, so the bar has an audible landmark.
  • Count eighths as “1 &”, triplets as “1 trip let” and sixteenths as “1 e & a”. Saying the syllables out loud keeps the inner notes even before your hands do.
  • The two six-note groupings feel different: sextuplets are three pairs (two triplets), sixteenth-note triplets are two threes. Accent the first note of each group to hear which one you are playing.
  • When one subdivision rushes, drop back to the one below it for a minute and return. Even sixteenths come from even eighths.

Subdivision questions

What is a subdivision metronome?

A metronome that sounds the notes between the beats, not only the beats: eighths, triplets, sixteenths or six-note groupings, with the quarter-note pulse kept audible as the anchor.

Which subdivision should I practise first?

Eighths, then triplets, then sixteenths. Most rhythm problems are uneven eighths; triplets teach the feel that swing and shuffles are built on.

Is it free?

Yes. The tempo and subdivision live in the URL, so a teacher can send a student the exact exercise as a link.
