Rhythm Builder

Listen to the beat and build the rhythm by placing notes and rests measure by measure.

About Rhythm Builder

Write what you hear, one measure at a time

Rhythm Builder plays a rhythm and you rebuild it by placing notes and rests in each measure. This is rhythmic dictation: turning sound into notation. You use it when you learn a passage by ear, write down a groove, or work out a rhythm your section keeps rushing.

Building is harder than choosing from a list because nothing is there to guide you. That's why it works. Every note you place is a decision about where a sound starts and how long it lasts, so the skill carries straight into reading and playing.

How to practice

  1. 01Listen once without touching anything. Count the beats out loud.
  2. 02Use Play Slow to find where each note starts, and mark those beats first.
  3. 03Fill in durations and rests so every measure adds up to the right number of beats.
  4. 04Build one measure completely before moving on to the next.
  5. 05Aim for 80% accuracy at Beginner before trying 3/4 or 6/8.

Every measure has to add up

The time signature tells you how many beats fill each measure. In 4/4, a half note (2 beats), a quarter (1) and two eighths (½ each) fill exactly four beats. If your measure comes up short or long, a duration is wrong somewhere.

A dot adds half the note's value: a dotted quarter lasts 1½ beats. A tie joins two notes into one longer sound, which is how rhythms cross the bar line or the middle of a 4/4 measure.

Who it's for

Students who are comfortable reading basic rhythms and ready to write them. It is also good for directors preparing students for sight-reading, theory classes or all-state auditions that include dictation.
