Tempo Trainer

Fast is easy once your slow becomes clean

A metronome that speeds up while you play, from the tempo where the part is clean to the one you are after, one small step at a time.

In the app you choose the step, how many bars each tempo holds, whether it climbs, comes down, or both, and whether it jumps in Steps or moves smoothly in a Glide, bar by bar.

How to get a part up to speed

From clean to fast, one step at a time: the way most teachers build speed, with the counting done for you.

  1. Find your clean tempoThe fastest you can play the part without a mistake and without tensing up. Start a few BPM under it.
  2. Set the targetThe tempo of the record, or just the next milestone. Today does not have to be the day you get all the way.
  3. Small steps, long enough to settleTwo to five BPM at a time, each held for at least one pass of the phrase.
  4. When a step breaks it, freezeHold that tempo until it is clean again, then let it climb on.
  5. Come back downEnd slower than you started. If the slow tempo still feels steady, the speed is really yours.

Tomorrow, start a step or two higher than today.

In the app

Set any climb you like

Any start and target, any step, any number of bars a step. The picture shows the whole climb, stairs or a slope, and how long it will take.

Five ways to shape it

  • Steps or GlideJump at each step, or let the tempo move bar by bar.
  • Up, Down, Up + DownSlow to fast, fast to slow, or up to the target and back.
  • FreezeHold the tempo where you are until it is clean, then let it climb on.
  • One more stepOn a good day, one tap at the target adds another step.
  • LoopStart the climb over when it ends, or stop at the target.

Starting points

Climbs to start from

Change the numbers to fit the part.

  • Guitar and bassThe riff at two thirds of the record, up 5 BPM every 4 bars, to the record’s tempo.
  • PianoA scale or a run from 60 to 96, up 4 every 2 bars, hands separately, then together.
  • Strings and windsUp + Down on the technical passage, so slow stays as clean as fast.
  • DrumsThe fill from your book, looped in Beats, up 5 every 4 bars.

Not only a click

Climb with a drum groove behind you

A part played to a click is not yet a part played with a band. The climb runs under whatever you practise with.

Questions

What people ask

What is a tempo trainer?

A metronome that changes the tempo for you while you play: a few BPM up, or down, every few bars, from a start to a target. Your hands stay on the instrument and your attention on the music, and the speed comes in steps small enough to play.

Can it slow down as well?

Yes. Down goes from fast to slow, and Up + Down climbs to the target and comes back again.

Is it free?

Yes, with a free account and no card: the Tempo Trainer runs on the metronome all day, every setting. Under a drum groove in Beats or a Shift sequence, it runs inside their ten free minutes a day, and unlimited with Pro.

Can it climb under a drum beat instead of a click?

Yes. In Beats the climb runs under a real acoustic drum groove, and you can loop just the bar you are working on while it speeds up.

Can I send my settings to someone?

With Pro, you can send the metronome as a link, the climb included: to a bandmate, or to a student if you teach. They open it and play, and with a free account the climb comes with it.

Does it run on my phone?

It runs in the browser on phones, tablets and laptops, and opens like an app from the home screen. Nothing to install.

Built by a drummer who teaches

I'm a drummer and teacher. Every part I have ever got up to speed got there the same way: slow until it was clean, then a few BPM at a time.

“For me, Timekeeper simply makes practice easier, more fun and more effective.”

I don't know of any other solution that brings these features together in the same way.
