# Free Online Cello — Play Warm Bowed Notes | Resonant > Play a free virtual cello with four open strings and sustained cello samples. Shape a low melody with your keyboard, mouse, or touch screen. Canonical page: https://resonant-appsoverflow.web.app/instruments/cello/ Creator: AppsOverFlow Guide updated: 2026-10-12 Give your melody a deeper voice. Explore the cello’s C2–G2–D3–A3 open strings, then use the labeled note controls to build a slow phrase or a steady low accompaniment. ## 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. Press and hold a string or labeled note control to sustain its tone. Release to fade, then leave a little space before the next note. Computer keyboard shortcuts offer the same note controls. ## Sound Cello samples from FluidR3 GM supply the bowed sound and are looped while notes are held. Bow direction, pressure, vibrato, and physical finger positions are not simulated. ## Build a slow line from low sustained notes Use three pitches that span the cello room’s low and middle controls. Longer holds make the register changes clear without adding many notes. Starting tempo: 60 BPM. Use Keep the beat for a steady pulse. 1: C2 (A) | 2: Keep holding C2 | 3: G2 (G) | 4: Keep holding G2 | 5: D3 (L) | 6: Keep holding D3 | 7: G2 (G) | 8: Release and rest 1. **Find the register changes.** Locate C2, G2 and D3 in the labeled controls. Their shortcuts are A, G and L. Use a comfortable volume, particularly with headphones. 2. **Hold for two beats.** At 60 BPM, hold C2 through beats 1 and 2, G2 through beats 3 and 4, and D3 through beats 5 and 6. Release each before moving to the next. 3. **Return without overlapping.** Play G2 on beat 7, then release for the last beat. Repeat as a single line rather than leaving the lower notes held underneath. **What to listen for:** Each new register should be distinct while the rhythm remains slow and even. Small speakers may make C2 less audible than D3. **Try next:** Replace the middle G2 with E2 using D. Keep the durations unchanged and compare the smaller move from C2. ## How do I record the cello in Resonant? 1. **Choose your playing controls.** Choose Play in 3D view or switch to Classic.
