Welcome to the Banjo Player's Toolkit.
When I originally built the Guitar Player's Toolkit, they were tools that I wanted to use, and still continue to use. I have taken those tools and applied them to banjo players. It provides everything from theory, tuning, chord composition, and tempo as well as some good practice utilities.
No ads, no subscriptions, and no internet required.

• Chord Master - Browse by key, build chords note-by-note, or place fingers on an interactive fretboard to discover what you're playing. Hear every chord played in whole, or arpeggiated.
• Chord Library - View thousands of chord diagrams. Search across chord types with strict or fuzzy matching. Filter by key, browse diatonic and borrowed chords, save favourites.
• Custom Chords - Create and name your own chords on an interactive grid. Auto-detect the chord name, play it back, and export/import to share with others.
• Transpose - Move song chords to any other key in seconds, with capo-aware transposition.
THEORY TOOLS
• Scales — 80+ scales across 14 categories: major, minor, modes, pentatonic, blues, jazz, Arabic, Indian ragas, Japanese, Chinese, and more. Interactive fretboard shows colour-coded positions with diatonic chord analysis. Tuning-aware for Standard, Low G, D Tuning, and Baritone.
• Scale Sharing — When playing songs with multiple chords, see where they overlap, if plucking individual strings, then know where the chord homes are (root, 3rd, and 5th). Minimise your hand movement by staying in the same general area.
• Circle of Fifths — Tap any key to explore its modes, and diatonic chords.
• Position Finder — Pick a fret and pick your key. Instantly see which scale modes fit there. Covers major, minor, harmonic minor, melodic minor, and chord tone patterns.
• Mode Converter — See exactly how any mode transforms into another — note by note, semitone by semitone.
PRACTICE TOOLS
• Note Practice — Drill fretboard note names at your own pace. Set tempo (5–120 BPM), choose strings and notes, display as text or fretboard diagram, and hear each note played. Includes a timed challenge mode.
• Metronome — 40–240 BPM with tap tempo, configurable time signatures, first-beat accent, and four click sounds (Woodblock, Click, Cowbell, Bell).
• Chromatic Tuner — Real-time pitch detection with ±1 cent accuracy, visual needle gauge, colour-coded feedback, and Hz display. Covers the full ukulele range (C3–C6).
