Free Online Metronome: Tap Tempo, Time Signatures, and Cross-Tab Sync

#A metronome that lives in your browser tab

A steady tempo is the foundation of every tight performance, and you should not have to buy hardware or install an app to get one. Onomo's Metronome is a visual and audio click that runs entirely in your browser. Open the page and you have a precise time-keeper ready to go, whether you are practicing scales, tracking a part, or teaching a student how to feel the beat.

It is built for musicians who want to lock in their timing, producers who need to set a tempo before recording, and teachers who want a clear visual reference their students can watch.

#Setting your tempo

The Metronome covers a wide range, from 20 to 300 BPM, and there are three ways to dial it in:

• Type it. If you already know your target tempo, enter the number directly.
• Nudge it. Use the plus and minus controls to step up or down one BPM at a time when you are hunting for the right feel.
• Tap it. This is the fastest way to match a tempo you can hear but cannot name. Use Tap Tempo and tap along with the beat in your head, or along to a track playing somewhere else. After a few taps, the Metronome reads the average and sets the BPM for you.

#Time signatures and subdivisions

Not every song is in straight 4/4, so the Metronome supports a range of time signatures: 4/4, 3/4, 6/8, 2/4, 5/4, and 7/8. You can also toggle an accent on beat 1 so the downbeat stands out and you always know where the bar starts.

Subdivisions are where practice really happens. Choose quarter notes, eighths, triplets, or sixteenths to hear the click break the beat into smaller pieces. This is the secret to cleaning up fast passages: slow the tempo down, turn on sixteenth-note subdivisions, and you can hear exactly where each note should land.

#Sound, visuals, and a count-in

You get several click sound styles so you can pick a tone that cuts through your instrument without becoming annoying, plus a volume control and a mute toggle. There is also a count-in of one or two bars, which is perfect for recording: hit play, get a full bar of clicks to set yourself, then come in right on time.

For people who track tempo with their eyes as much as their ears, there are three visual modes:

• A ring that fills around the beat.
• Bars that pulse with each click.
• A pendulum that swings like a classic mechanical metronome.

#Cross-tab sync with your Onomo sessions

This is the feature that sets this Metronome apart. If you have Onomo's Studio playing in another browser tab, the Metronome automatically locks to that tempo and beat. You do not have to re-enter anything. Open the Metronome alongside whatever you are working on and it follows along, staying in step with your project so the click and your session never drift apart.

#Tips to get more out of it

• Use Tap Tempo to learn songs by ear. Tap along to a recording, read the BPM, and you instantly know the tempo to practice at.
• Turn on the count-in before you record. A one or two bar count gives you time to settle in so your first note is on the grid.
• Lean on subdivisions for clarity. When a part feels rushed or sloppy, a smaller subdivision shows you exactly which notes are early or late.
• Pick a click sound that contrasts your instrument. A higher, sharper click is easier to hear over a bass; a softer tone sits better under vocals.
