Today’s rhythm changes at midnight. New rhythm gives you another at the same level; Today’s rhythm brings the daily one back.

How to read it

  1. Count the beat first. Say “1 2 3 4” steadily before you start, as the count-in does.
  2. Say the counting under the notes, keeping the beat even. Counts in brackets are held notes or rests: keep counting, but don’t clap.
  3. Clap it while you count, then press Play to hear whether it matches. Choose the Note sound to hear how long each note lasts as well as where it starts.

Use it for rhythm sight reading in class or at home: read each new rhythm on sight, then check it with Play. New to reading rhythm? How to read rhythm explains note lengths and counting step by step.

Using it in class

  • A warm-up as students come in. Put today’s rhythm on the board full screen; the class reads it together once everyone is in.
  • Echo and check. Half the class claps, the other half checks against Play. Then swap.
  • Your counting system. Choose numbers, ta / ti-ti or Takadimi to match how you teach, or None to let students write the counting in.
  • The same rhythm at home. Students who open the page tonight see the rhythm you did in class.

Questions

What’s in each level?

Level 1: quarter notes, pairs of eighth notes and quarter rests. Level 2 adds half and whole notes and half rests. Level 3 adds dotted half notes and a dotted quarter with an eighth. Level 4 adds sixteenth notes and some rhythms in 3/4.

Why are some counts in brackets?

They’re beats you count but don’t clap: the rest of a held note, or a rest. Keeping them in your head is what keeps the beat steady.

Is it really the same for everyone?

Yes. The day’s rhythm comes from the date, so everyone who opens it on the same day at the same level and length sees the same rhythm.

Can I change the speed while it plays?

Yes. A new speed or sound starts from the next time through: turn on Repeat and it plays again at the new setting, so the beat never changes halfway.
