Why I Built Form & Time

I've spent a lot of time practicing with a metronome, and a lot of time playing music that doesn't sit neatly inside a simple loop.

Practicing Music Where Form Matters

Most of the music I play—especially jazz—has form that matters. Thirty-two bar tunes. Twelve-bar blues. Sixteen-bar forms. Sometimes odd lengths. The point isn't just keeping time, it's knowing where you are inside the tune and feeling how long things last.

Most metronomes don't deal with that. They loop. That's fine for a lot of things, but it doesn't reflect how this music moves. Instead of looping endlessly, the music runs for the length of the tune.

The Workaround That Came Before

For years, my workaround was to program practice grids in Ableton Live. It worked, but it was slow and clunky for something as basic as sitting down to practice.

Ableton is powerful, but it's also heavy. If it takes too long to set something up, you're less likely to do it at all.

What Form & Time Is

I wanted something simpler.

Form & Time started as a web-based metronome I built for myself. It lets me set the time signature, tempo, and—most importantly—the form. That's the whole difference.

For example, setting a 32-bar form at 120 bpm and letting it run without looping changes how I listen and pace myself.

What It Is (and Isn't)

I built it to practice jazz tunes, but it isn't tied to any style, method, or approach. It doesn't tell you what to play or how to play it.

It doesn't care whether you're working on time, touch, pacing, transitions, or just trying to stay oriented over longer stretches.

It's just a tool that acknowledges form.

You could use it to practice a standard. You could use it to work on endurance. You could ignore the form entirely and treat it like a regular metronome. That part is up to you.

No Rules Attached

There are no rules attached. There's no philosophy baked in. I didn't build it to teach anything or to convince anyone of a way of practicing.

I built it because I kept running into the same limitation and wanted something that got out of the way quickly.

If it's useful to someone else, great. If not, that's fine too.

It solves a practical problem I had, and now it's available.
