# Free Online Marimba — Play Chromatic 3D Bars | Resonant > Play a free virtual marimba with 25 chromatic 3D bars and warm sampled sounds. Tap both rows, shape your touch, and record a melody. Canonical page: https://resonant-appsoverflow.web.app/instruments/marimba/ Creator: AppsOverFlow Guide updated: 2026-10-12 Discover 25 chromatic notes from C3 to C5 across the natural and raised accidental rows. Every 3D bar plays its own pitch. Classic view retains 15 diatonic notes for a compact starting layout. ## How to play In 3D view, choose Play to tap, strum, or glide across a playing surface. Hold keys or wind surfaces to sustain a note. Choose Rotate to inspect the model; scroll or pinch to zoom. Use the labeled note controls or computer keys for chords and the full range. Classic view provides the original illustrated playing surface. Strike either 3D row or sweep across the bars. Play close-up enlarges a section; All pitches exposes the full chromatic range as labeled controls. Classic keyboard shortcuts retain their original notes. ## Sound Marimba samples provide a warm attack and a rounded, resonant decay. ## Keep a returning note while the pattern changes Use G3 as a repeating anchor while the lower notes move. The warm decay lets you hear how the two halves overlap without becoming identical. Starting tempo: 72 BPM. Use Keep the beat for a steady pulse. 1: C3 (A) | 2: G3 (G) | 3: E3 (D) | 4: G3 (G) | 5: D3 (S) | 6: G3 (G) | 7: F3 (F) | 8: G3 (G) 1. **Locate the compact controls.** Find C3, D3, E3, F3 and G3. Their shortcuts are A, S, D, F and G. Set Keep the beat to 72 BPM and four beats per bar. 2. **Alternate with the anchor.** Play the pattern one note per beat. G3 returns on every even-numbered beat; avoid hitting it early as you change the lower note. 3. **Listen to the two halves.** Repeat the eight beats, keeping the tempo unchanged. The first half uses C3 and E3; the second replaces them with D3 and F3. **What to listen for:** The repeated G3 should connect the two halves. Let each bar ring naturally while keeping the new attacks evenly spaced. **Try next:** Move the repeating anchor to C4 using K and keep the lower-note sequence. Compare the wider pitch gaps. ## How do I record the marimba in Resonant? 1. **Choose your playing controls.** Choose Play in 3D view or switch to Classic. Tap a playing surface, use the labeled note controls, or press a computer-key shortcut to enable sound. 2. **Record your idea.** Press Record above the instrument, then play your phrase. This records studio audio without using your microphone. Each take can last up to five minutes. 3. **Listen and keep a copy.** Press Stop, open Recordings, and listen to the take.
