Fretuno: Guitar Ear Training

Want to recognize notes by ear, find them faster on the guitar fretboard, and play with more confidence? Fretuno combines guitar ear training, fretboard learning, and practical music theory in short, focused practice sessions.

Listen, see, and play

Hear a note or interval, see where it appears on the interactive fretboard, then play it on your guitar. This connects what you hear with what you see and play, so fretboard knowledge becomes a practical skill instead of a collection of isolated patterns.

Build essential guitar skills

• Recognize notes and pitch differences by ear

• Practice melodic and harmonic intervals

• Learn the names and positions of notes across the guitar fretboard

• Find notes and intervals on an interactive fretboard

• Improve your musical reflexes with focused exercises

• Build a stronger foundation for improvisation, songwriting, and playing by ear

Master your guitar fretboard

Choose your guitar tuning and practice on a clear visual fretboard. Connect note names with their positions across the strings and frets, gradually building a practical map of the entire neck.

Daily practice that adapts to you

Fretuno uses your recent answers, progress, and musical goals to shape each session. Your practice may include a warm-up, review, weaker areas, and new challenges. A few focused minutes each day can help you steadily improve your musical ear and fretboard knowledge.

Track your progress

Review your accuracy, practice history, daily streaks, and skill development. See which areas need more attention and build confidence through consistent practice.

Practice offline

Core exercises, progress tracking, and generated instrument sounds are available without an internet connection. Choose a clean guitar, piano, or synth sound and practice wherever it suits you.

Optional microphone feedback

Selected exercises can use your device microphone to recognize a stable single note played on your guitar and provide feedback. Audio is analyzed locally on your device during the exercise. Recordings are not saved or uploaded.

For beginner and developing guitarists

Fretuno can help whether you are starting to learn guitar fretboard notes, improving interval recognition, studying music theory, preparing to improvise, or becoming more comfortable playing by ear.

Start your daily ear training and make every note on the fretboard feel familiar.
