Store description excerpt
See exactly what to play over any chord. Bass players don't read chord diagrams — you read changes. You're handed a progression and the only question that matters is: which notes lock with this chord, and where do they sit under my hand? Fretionary Bass answers that instantly. Pick a root and a chord, and the strong notes — root, 3rd, 5th, and 7th — light up across your entire neck, color-coded so the tones that define the chord jump right out. The matching scale sits dimmed underneath, so your safe notes are always in view. It's faster than thinking, and it's built for bass: your string count, your tuning, your hand position. THE CHORD-TONE OVERLAY • Root, 3rd, 5th, and 7th lit up in distinct colors across the whole neck • The suggested parent scale dimmed underneath — toggle it on or off • Lock a 4-fret window to see exactly what falls under your hand • Tap any note to hear it — real bass samples, pitched to the note • Interval labels (R 3 5 7), note names, or none YOUR BASS, YOUR TUNING • 4, 5, and 6-string necks — the whole fretboard follows your tuning • Standard, Drop D, low-B 5-string, 6-string, and more • Every overlay, scale, and arpeggio recalculates for your instrument MORE ON THE NECK • Scales and modes mapped across the fretboard, color-coded by interval • Arpeggio view — chord tones only, the bass staple • Custom mode — highlight any set of notes you want • Built-in metronome for tight practice • A daily scale or chord pick, plus a practice streak to keep you sharp WORKS ANYWHERE • Fully offline — no account, no sign-up, nothing leaves your device • Clean, fast, dark interface made to glance at mid-song Start free with the core overlay, essential scales, and standard tuning. Unlock everything — all chords and 7ths, every scale and mode, all tunings, and custom mode — with Fretionary Bass Pro (monthly, or a one-time lifetime purchase). Stop guessing the changes. Start locking in. Privacy Policy: https://fretionary-bass.com/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
