The strong notes — root, 3rd, 5th, 7th — lit up right where your hand is. On your bass, in your tuning. Stop guessing the changes and start locking in.
Pick a root and chord and the root, 3rd, 5th and 7th light up across the neck — color-coded so the notes that lock with the chord pop. The matching scale sits dimmed underneath.
String count is built in. Standard, Drop D, low-B 5-string, 6-string and more — the whole fretboard recalculates for your bass and your tuning.
The full scale and mode reference, plus a chord-tone arpeggio view — the bass staple — mapped across the neck and color-coded by interval.
Pin the overlay to a 4-fret window and everything outside dims. See exactly what falls under your hand without losing the rest of the neck.
Tap any note to hear it — recorded bass samples, pitched to the exact note, so it sounds like a real string fretted up and down the neck.
Hand-pick any set of notes to highlight on the neck. Build your own shape, map a riff, or sketch an idea — your fretboard, your rules.
Tuning isn't an afterthought — it's the foundation. Pick your instrument and string count, and every note on the neck follows. From a 4-string in standard to a low-B 5 or a wide 6.
You're handed the changes. Three taps and you know exactly which notes lock with the chord — and where they sit under your hand.
Set the root and chord quality. Triads, sixths and sevenths — the chords that actually show up on a chart.
Root, 3rd, 5th and 7th light up across the neck. The 3rd pops — it's the note that defines the chord. The parent scale sits dimmed underneath.
Pin a 4-fret window to your hand and the rest of the neck dims. Tap to hear it. Now you're playing the changes, not hunting for them.
