• What scales can I use over this chord progression?
• How do I learn the notes on the guitar fretboard?
• How do I find chord tones for soloing?

Chord Finder:
Tap notes on the guitar fretboard to identify chord names, inversions, slash chords, extended chords, altered chords, and possible alternate names. Use it to understand chord shapes, check voicings, and learn what chord you are playing.

Scale Finder:
Find compatible scales and modes from selected notes, chords, or full progressions. Explore major, minor, pentatonic, blues, modal, jazz, harmonic minor, melodic minor, exotic, and advanced scale sounds.

Progression Builder:
Create chord progression loops with drums, guitar playback, tempo control, and groove options. Find scales that fit the key, tonal center, and chord movement. Practice pop, rock, blues, jazz, metal, folk, country, funk, worship, modal jams, and more.

Progression Library:
Practice with 140+ ready-made progressions, including 24-bar jam-along tracks for lead guitar, soloing, improvisation, chord-tone targeting, and backing-track style practice.

Fretboard Trainer:
Learn the fretboard by practicing notes, intervals, scale degrees, and chord tones directly on the guitar neck. Use goals, miss review, auto next, position practice, random fretboard ranges, and beginner-friendly difficulty levels.

Ear Trainer:
Train relative pitch with guitar sounds. Practice intervals, chord quality, and scale degrees with easy, medium, and hard lessons.

Circle of Fifths:
Explore major keys, relative minor keys, scale notes, diatonic chords, nearby keys, borrowed color, secondary dominants, and common progressions. Load common progressions into the Progression Builder for practice.
