Yes. This virtual bass guitar is free to play in your browser, with no download or account required. Bass samples let you explore low-register riffs and bass lines.
Pick mode starts enabled. Move your mouse across fretboard notes to play them, then move back over a note to play it again. If you hear nothing at first, click a note to enable browser audio. Click the Pick mode: ON button to turn it off for normal click-to-play controls. On a phone or tablet, tap notes to play.
Turn on Keyboard keys above the fretboard to see each note’s shortcut. A shift arrow means hold Shift while pressing that key. Keyboard labels start hidden, and symbol shortcuts use a US keyboard layout.
Check Note labels above the fretboard. Labels start hidden for a cleaner view. This setting is separate from Keyboard keys, so you can show either set of labels or both.
The fretboard highlights notes as they sound, whether you play them yourself or use song playback. The highlights help you follow a melody even when labels are hidden.
Follow playback scrolls the fretboard sideways to keep the sounding note in view. This is useful on narrow screens. Automatic scrolling pauses while Pick mode is enabled so the notes do not move underneath your mouse.
Open Note editor and enter a sequence using the instrument’s keyboard shortcuts, then press Play. Use Stop to end playback and the note-duration control to change the speed.
Click or tap a note first: browsers may block audio until you interact with the page. Check your device volume, the browser tab’s mute setting, and your audio output. An internet connection is needed to load sounds that are not already cached.
The bass guitar is the heartbeat of modern music — the low-end foundation that holds every song together. From the warm thump of a jazz walking bass line to the driving punch of rock and the deep sub frequencies of hip-hop and funk, the bass is what makes people move. Our free virtual bass guitar lets you feel that low-end power right in your browser, with no amp or instrument required.
This free online bass is part of ButtonBass, a music platform that has been helping people make music in the browser for over a decade. The bass joins our family of string instruments alongside the acoustic, electric, and distorted guitars and the banjo — all playable the same way, with a clickable fretboard, keyboard support, animated strings, and built-in songs.
Click anywhere on the interactive fretboard to hear deep, resonant bass tones ring out instantly, or use your keyboard keys to play notes. The layout shows every note position across the neck, so you can explore bass lines, learn how the strings relate to each other, and experiment with different patterns. Animated string vibrations give visual feedback as you play.
Pre-loaded songs are ready for instant playback — just hit Play. Use Stop to halt playback, Next and Previous to move between songs, and Clear to empty the note box. To build your own bass line, type or paste a sequence of note letters into the text box and press Play. Adjust the tempo value to speed things up or slow them down so you can lock into the groove at your own pace.
The electric bass guitar was invented in the 1950s, when Leo Fender introduced the Precision Bass and gave bands a fretted, amplifiable instrument that could replace the bulky upright double bass. It quickly became essential to rock and roll, soul, and Motown, and over the following decades it shaped the sound of funk, reggae, disco, metal, and hip-hop. Where the upright bass once anchored jazz and big-band music, the electric bass made the low end portable, loud, and rhythmically precise.
That history is why the bass sits where it does in a mix: it bridges the rhythm of the drums and the harmony of the chords, locking with the kick drum to create the groove that everything else rides on.
Fingerstyle — plucking with the index and middle fingers — is the most common approach and gives a round, punchy tone. Slap and pop, popularized in funk, uses the thumb and fingers percussively for that snappy, rhythmic sound. Pick playing delivers a brighter, more aggressive attack favored in rock and punk. Walking bass lines are the backbone of jazz, moving smoothly between chord tones. You can explore the feel of these styles on the virtual bass by experimenting with which notes you play and how quickly you trigger them.
Bassists like James Jamerson, who played on countless Motown hits, and Jaco Pastorius, who redefined what the fretless bass could do, showed the instrument's melodic potential. Flea of the Red Hot Chili Peppers brought slap-funk energy to rock, while Les Claypool turned the bass into a lead voice all its own. Their work proves the bass is far more than a supporting instrument — it can be expressive, virtuosic, and unforgettable.
Start slow. Lower the tempo, play a built-in song, and watch which strings light up so you can connect the keys to the notes. Lock in with a steady pulse before you add movement — great bass playing is as much about timing as it is about the notes. Try building a short repeating line in the note box to feel how a groove locks in. Because everything runs in your browser, you can test ideas instantly without an amp or setup, on desktop, tablet, or phone.
Beyond the bass, ButtonBass offers a growing library of browser-based instruments and games.

Every tool is free, works on any device, and requires nothing more than a modern web browser.
