Frequently Asked Questions
Do I need to install anything to play?
No. The bass loads real recorded samples in your browser and plays them with the Web Audio API. Just open the page and click a string to start.
How do the keyboard shortcuts work?
The four rows of keys on your keyboard correspond to the four bass strings (G, D, A, E from top to bottom). Each key along a row moves one fret higher, so the number row plays the G string, the Q row plays the D string, the A row plays the A string, and the Z row plays the E string.
How do I change the bass sound?
Click the bass button in the toolbar to open the sound picker. You can choose between finger, pick, fretless, acoustic, slap, and synth bass tones.
What does Mark mode do?
Click Mark, then click positions on the fretboard to tag them. Each marked note is colour-coded and labelled with its note name. Press the spacebar to play all marked notes in sequence. Hold Alt while marking to spell a note with a flat (♭) instead of a sharp (♯).
How do I share a bass line or scale?
Mark the notes you want, then copy the URL from your browser's address bar. Anyone who opens that link will see the same notes pre-marked on their fretboard.
What tuning does the bass use?
Standard tuning: E A D G from the lowest (thickest) string to the highest (thinnest) — the standard tuning for a four-string bass guitar.
Why is there no sound when I first open the page?
Browsers block audio before any user interaction, and the samples take a moment to load. Click a string once the samples have loaded and audio will play for the rest of the session.
