What's New in Guitarist Buddy

2.4

September 24, 2026

* Added ukulele samples * Added major blues and harmonic minor as scale types which can be displayed * Common Progressions — a new Progression Builder view with common patterns like I-IV-V, I-V-vi-IV, 12-bar blues, ii-V-I, and minor variants. Similar in feel to the existing Chord Builder flow. A library of named progressions (I-IV-V, I-V-vi-IV, 12-bar blues, etc.) that auto-populate the Key Explorer's chord selection for the current key. * Chord Transition Helper — tap two chords and get common fingering pivot points / suggested fingering paths between them. * Capo Calculator — enter a Song Key and a preferred Play In key, get the capo fret plus a translated chord chart. A guitarist hears a song, finds out it's in Eb, doesn't want to play all barre chords — the capo tool tells them capo 1, play in D or capo 3, play in C. You'd show the original key, let them pick a target chord-shape key, and it outputs capo fret. * modal characteristic notes and scale degree labels on the diatonic chord buttons. * Reverse chord lookup - tap frets on a fretboard diagram and identify what chord it is chromatically, across all 12 roots and all qualities, with no dependency on any selected key. * Improvements on Melody Builder - to include and suggest several guitar techniques to use as melodies, solo with in the context of the current key
