OzzLoop

Play piano, guitar and chord loops online

OzzLoop is a free online piano, virtual guitar and chord progression looper. Play notes yourself or build a repeating accompaniment, directly in your browser. There is no account, time limit or paid mode.

1. Play an instrument

   Choose Piano or Guitar. Tap piano keys to play, or swipe across the guitar strings to strum. On a computer, A W S E D F T G Y H U J play the first piano octave. K and the keys to its right continue into the second octave. Z lowers and X raises the octave range. Keys 1–6 pluck the guitar strings.

2. Build a chord progression

   Tap a chord to hear it. Tap an empty slot to add that chord, or drag a chord into one of the 10 slots. Drag filled slots to reorder them. Use the small × to remove a chord.

3. Loop at your own tempo

   Set a tempo between 30 and 240 BPM and choose 1, 2, 4, 8 or 16 beats per chord. Press Play loop to repeat your progression. Empty slots are skipped. Stop loop ends the accompaniment.

4. Explore guitar rhythms and arpeggios

   Choose classical, acoustic or electric guitar. Four rhythm patterns and four arpeggio patterns shape your chord loop. The same progression stays available when you switch between piano and guitar.

Questions & answers

Can I play piano and guitar for free?

Yes. All instruments, chord slots, rhythms and arpeggios are available without a subscription, account or usage countdown.

Can I play a melody over my chord loop?

Yes. Start your chord progression, then play piano notes or guitar strings over the repeating accompaniment.

Why is there no sound before I tap?

Browsers start sound after a user gesture. Tap a key, chord or Play loop first. If needed, raise your device volume and check its sound output.

Does OzzLoop record my playing?

No. OzzLoop does not record or upload your performance. Chord slots, tempo and instrument preferences are saved locally in this browser. Sound stops when you leave the page or switch away.
