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
99 scales: 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, by key signature, by root or by fingering — 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 DIAGRAMS (PRO)
See up to nine fingering patterns side by side, or the whole 24-fret neck in one view. Compare modes, keys, parallel scales or chromatic roots, hear any shape with a tap, and save the diagrams as an image.

🔍 SCALE & CHORD FINDER (PRO)
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 (PRO)
Start slow, let the trainer raise the tempo every few rounds up to a target BPM. It can shift key, root, mode 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, or hide whole strings, to focus on one position.

🎵 JAM MODE (PRO)
Build a chord progression, give every bar its own strumming pattern, and play along. [47] built-in strumming patterns, accented and muted variants, sixteenth-note double strokes, arpeggios, and musical figures with real rhythmic push and pull — the kind of bass-then-roll pattern a live player actually uses. Swing feel, metronome, count-in, loop and speed-up per round. Twenty slots for your own patterns, ten for whole jams.

🎯 CHROMATIC TUNER — FREE FOR EVERYONE
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.

🌍 ENGLISH & HUNGARIAN · 🤚 TRUE LEFT-HANDED MODE · 🎨 SIX THEMES INCLUDING AMOLED · 🖥️ FULLSCREEN VIEW · 💾 BACKUP AND RESTORE

Whether you are finding your first pentatonic box or working modal fluency across all 24 frets, this is a practice tool you will open every day.
