Switch between sharps and flats, show octave numbers, label the neck with intervals or Roman numerals, flip it for left-handed players, and print a full-neck chart.

Frequently Asked Questions
A standard 4-string bass is tuned E A D G from the thickest string to the thinnest — the same notes as the four lowest guitar strings, one octave lower. Each fret raises the pitch by one semitone, so the notes run through all 12 pitches (C, C sharp, D, D sharp, E, F, F sharp, G, G sharp, A, A sharp, B) and repeat from the 12th fret up. Tap any note on the bass fretboard to see its name and hear it.
Yes. Pick a 5-string tuning (B E A D G, or E A D G C for high C) or the 6-string tuning (B E A D G C) and the neck redraws with that many strings. 4-string tunings include standard E A D G, Drop D, half step down, full step down, Drop C and B E A D.
9 bass tunings: Standard 4-string (E A D G), Drop D (D A D G), half step down, full step down (D G C F), Drop C (C G C F), BEAD 4-string (B E A D), Standard 5-string (B E A D G), 5-string high C (E A D G C) and Standard 6-string (B E A D G C).
Every note plays at true bass pitch — the open low E is E1, 41.2 Hz, one octave below a guitar's low E. There is no dedicated bass sample set yet, so the notes are the site's sampled clean electric guitar played one octave down. Small laptop and phone speakers barely reproduce the lowest notes; headphones or a bass amp let you hear them properly.
Yes. Set Labels to "Intervals (1 2 3)" to show every note as a scale degree counted from an Interval Root you choose, or "Roman (I II III)" for Roman numerals. Bass lines are mostly built from the root, 3rd, 5th and octave, and seeing those numbers on the neck is the quickest way to learn a pattern you can move to any key.
Yes. Set Fretboard to Left-handed and the neck mirrors so the nut is on the right. The setting is shared with every fretboard on the site, guitar and bass.
