Guitar Scale Master

Most scale apps show you a diagram. Guitar Scale Master lets you HEAR it, jam over it, and build your own practice out of it.

Pick a root and a scale — every note lights up on a full, interactive fretboard, played back through a real sampled instrument. Not a beep. Not a sine wave. A guitar.

🎸 REAL INSTRUMENT SOUND
Nylon and steel-string acoustic, jazz and clean electric, overdrive, distortion, bass and banjo. Adjustable strum speed, sustain and note gap — so a chord sounds strummed, not triggered.

🎼 A SERIOUS SCALE LIBRARY
Major and minor modes, harmonic and melodic minor, pentatonics, blues, symmetric and exotic scales, Hungarian folk scales, arpeggios and chord shapes — organised into clear categories instead of one endless list.

✋ EVERY WAY YOU ACTUALLY PRACTISE
Full neck. Single string. Classic box positions (with or without reaching below the starting fret). 1, 2, 3, 4 and 5 notes per string. Two-string patterns. Switch instantly — the whole neck recalculates around you.

➡️ STEPPING THAT MAKES SENSE
Step by fret, by degree, by mode or by key signature — and the arrows tell you in advance where you are about to land. Or use Fix stepping: the shape stays put while the colouring moves through the degrees.

🔍 SCALE & CHORD FINDER
Tap a few notes anywhere on the neck and the app tells you which scales and chords contain them, with a match percentage. Tap a result to jump straight into it.

🎹 INSTRUMENTS & TUNINGS
6 and 7-string guitar, 4 and 5-string bass, ukulele — with standard, drop D/C, half and whole step down, open tunings, DADGAD and more.

🔁 BUILD YOUR OWN SEQUENCES
Thirds, fourths, broken triads, sweeps, mechanical string-and-fret runs — write your own patterns with a compact syntax, or start from a large preset library. Save your favourites to slots.

⏱️ TEMPO TRAINER
Start slow, let the trainer raise the tempo every few rounds up to a target BPM. It can shift key or degree automatically, so your practice never goes on autopilot.

🎨 SEE THE CHORD TONES
Roots, triads, sevenths and power chords coloured directly on the fretboard, absolute or relative. Dim any fret range to focus on one position.

🎵 JAM MODE (PRO)
Build a chord progression, give every bar its own strumming pattern, and play along. 36 built-in strumming patterns, accented and muted variants, arpeggios, and musical figures with real rhythmic push and pull — the kind of bass-then-roll pattern a live player actually uses. Metronome, count-in, loop and speed-up per round. Twenty slots for your own patterns, ten for whole jams.

🎯 CHROMATIC TUNER (PRO)
Tune by ear or by mic, with adjustable reference pitch and a reference tone for every string.

🎼 CIRCLE OF FIFTHS
Keys, relative minors and diatonic chords at a glance — and one tap loads any of them.
